Answer:

birds-eye view perspective

Explanation:

If someone asked me to design an office building, I would draw it from a birds-eye view perspective. I would draw it this way so I could map out where everything in the office would go and make sure I have enough space for everything. I would also draw it this way in order to clearly see where everything would go in the office. For instance, cubicles/desks could go in the bottom left corner, while the boss's office could go in the top right. It would be easier to organize and it would be easier for me to look back on when I need to actually design the office later.

TQM is an acronym meaning "total quality measurement."

NMB= name me brainiest.

The statement is false. TQM is an acronym for "Total Quality Management," not "Total Quality Measurement."

Total Quality Management (TQM) is a management approach focused on continuously improving the quality of products, services, and processes within an organization. It emphasizes the involvement of all employees and aims to create a culture of quality throughout the entire organization.

TQM encompasses various principles and practices, including customer focus, continuous improvement, employee empowerment, and data-driven decision-making. It involves the systematic management of quality across all aspects of an organization, from product design and production to customer service and support.

While measurement is an important component of TQM, it is not the sole focus. TQM emphasizes a holistic approach to quality management, encompassing not only measurement but also process improvement, customer satisfaction, employee involvement, and other factors that contribute to overall organizational excellence.

Therefore, the statement that TQM stands for "Total Quality Measurement" is incorrect. The correct expansion of TQM is "Total Quality Management."

Answer:

72 years

Explanation:

The degree of consideration is the same for both bridges = 90%

Height  of first highway bridge( d1 ) = 5 ft

Time to consolidation ( t1 )= 4.5 years

Height of second bridge ( d2 ) = 20 ft

Time to consolidation ( t2 ) = ?

we will apply this relation below

Tv = Cv * t / d^v

Tv = constant

for a single drainage condition : t ∝ d^v hence; d = H

∴ \(\frac{t_{2} }{t_{1} } = (\frac{d_{2} }{d_{1} })\)^2

t2 = t1 ( d2/d1 )^2

   = 4.5 ( 20 / 5 )^2

  = 72 years

Answer:Falling or flying objects on a worksite can expose workers to relatively minor injuries, such as cuts and abrasions, as well as more serious injuries, such as concussions or blindness. Working beneath scaffolds or other areas where overhead work is being performed puts workers at risk from falling objects. Flying objects become a concern when workers are using power tools or performing tasks that involve pushing, pulling or prying.

Explanation:General

Always wear hard hats when work is being performed overhead or when other work conditions call for it.

Stack materials securely to prevent them from sliding, falling or collapsing.

Overhead work

Secure all tools and materials to prevent them from falling on people below.

Use toe boards or guardrails on scaffolds to prevent objects from falling. Alternately, use debris nets or catch platforms to grab falling objects.

Machine use

When working with machines or power tools that can produce flying particles, wear safety glasses, goggles or face shields.

Inspect tools prior to use, and be sure all guards are in place and in good working condition.

Allow only properly trained workers to use power-actuated tools.

Cranes/hoists

Whenever possible, avoid working under moving loads.

Erect barricades and post warning signs at hazardous work zones.

Inspect cranes and hoists prior to use to ensure all components are in good working order, including wire rope, lifting hooks and chains.

Never exceed the lifting capacity of cranes and hoists.

Compressed air

Reduce compressed air for cleaning to 30 psi, and always use proper personal protective equipment and guarding.

Never clean clothing with compressed air.

a) Boost converter is a switching converter that converts the input voltage to a higher output voltage level. The boost converter output voltage is always greater than the input voltage. Boost converters are also known as step-up converters because the output voltage is higher than the input voltage. Applications: DC power supplies, laptop adapters, mobile chargers, electric vehicles, etc.

b) continuous conduction mode can be derived as follows:

Vo / Vin = 1 / (1 - D)

c) The value of inductor that will ensure continuous current conduction mode is 26.7 μH.

a) The main applications of boost converters include:

b) In continuous conduction mode, the boost converter operates with a continuous current flowing through the inductor. The steady-state waveform and switch ON-OFF equivalent circuit can be used to derive the expression for the voltage gain of the boost converter.

Let's denote the duty cycle of the switch as 'D' (D = Ton / T, where Ton is the switch ON time and T is the switching period). The voltage gain (Vo / Vin) of the boost converter in continuous conduction mode can be derived as follows:

Vo / Vin = 1 / (1 - D)

c) Given that the input voltage varies from 24 V to 72 V and the maximum output power is 240 W. We know that Power P = V x I, where V is voltage and I is current. Inductor current (I) in the continuous conduction mode is given

asIL = (Vout x D x T)/L Where, T is the switching period

L = (Vin - Vout) x D x T/ (2 x Vout x ILmax) ILmax is the maximum inductor current at the output side.

ILmax = Pmax / Vout

Let's calculate the maximum inductor current:

ILmax = 240 W/ 96 V = 2.5 A

Assuming the duty ratio D to be 0.5, and switching frequency f as 50 kHz, the switching period T is given as:

T = 1/f = 20 μs.

The output voltage is Vout = 96 V and input voltage is 72 V.

Thus, the voltage across the inductor is given as follows:

Vs = Vin - Vout = 72 V - 96 V = -24 V (negative because it is in step-up mode)

Substituting these values in the above equation, we get

L = (72 - 96) x 0.5 x 20 x 10^-6 / (2 x 96 x 2.5) = 2.67 x 10^-5 H = 26.7 μH

The value of inductor that will ensure continuous current conduction mode is 26.7 μH.

Erik Erikson proposed a theory of psychosocial development, which suggests that individuals go through eight stages of development throughout their lives.

Each stage is characterized by a psychological crisis that needs to be resolved in order for healthy development to occur. Here are the eight stages of Erikson's theory. Trust vs. Mistrust: This stage occurs during infancy, from birth to about 1 year old. The crisis involves developing a sense of trust in the world, particularly in one's caregivers, and feeling secure in their care.

Autonomy vs. Shame and Doubt, This stage occurs during early childhood, around 1 to 3 years old. The crisis centers around developing a sense of independence and autonomy while still being guided by caregivers. Failure to develop autonomy can lead to feelings of shame and doubt.

A supply chain is the network of all the individuals, organizations, resources, activities, and technology involved in the creation and sale of a product. A supply chain encompasses everything from the delivery of source materials from the supplier to the manufacturer through to its eventual delivery to the end user.

A system that calls for subassemblies and components to be manufactured in very small lots and delivered to the next stage of the production process just as they are needed is known as a Just-in-Time (JIT) system.

JIT is a manufacturing philosophy that aims to eliminate waste by producing only what is needed, when it is needed, and in the exact quantity required. This system requires careful coordination between suppliers, manufacturers, and customers to ensure that materials and parts are delivered on time and in the right quantities.

JIT has many benefits, including lower inventory costs, improved efficiency, reduced lead times, and higher quality products. However, it also requires a high degree of planning, communication, and flexibility to be successful. Overall, JIT is a complex but powerful system that can help organizations streamline their production processes and improve their bottom line.

The displacement of end D with respect to end A is \(-0.488 \times 10^{-3}\;m\)

Given the following data:

To determine the displacement of end D with respect to end A:

First of all, we would do a sectional cut of the circular rods at point A and then determine the sum of forces acting on it:

\(\sum F=0\\\\ 10000+N_1=0\\\\N_1 = -10000\;N\)

Mathematically, the displacement of a circular rod is given by this formula:

\(d = \frac{NL}{AE}\)

Where:

Substituting the given parameters into the formula, we have;

\(d_1 = \frac{-10000 \times 0.435}{\frac{3.142 \times 0.02^2}{4} \times 68.9 \times 10^9} \\\\d_1 = \frac{-4350}{0.0003142 \times 68.9 \times 10^9}\\\\d_1 =-0.201 \times 10^{-3}\;meter\)

For section cut BC:

\(\sum F=0\\\\ 10000-20000+N_2=0\\\\N_2 = 10000\;N\)

\(radius = outer\;radius^2 - inner\;radius^2\\\\radius = 0.04^2 -0.03^2=0.0007\;m\)

\(d_2 = \frac{10000 \times 0.435}{\frac{3.142 \times 0.0007^2}{4} \times 68.9 \times 10^9} \\\\d_2 = \frac{4350}{0.00054985 \times 68.9 \times 10^9}\\\\d_2 =0.115 \times 10^{-3}\;meter\)

For section cut D:

\(\sum F=0\\\\ -20000-N_3=0\\\\N_3 =- 20000\;N\)

\(d_3 = \frac{-20000 \times 0.435}{\frac{3.142 \times 0.02^2}{4} \times 68.9 \times 10^9} \\\\d_3 = \frac{-8700}{0.0003142 \times 68.9 \times 10^9}\\\\d_3 =-0.402 \times 10^{-3}\;meter\)

For the total displacement:

The total displacement is equal to the displacement of end D with respect to end A.

\(d_T = d_1 +d_2+d_3\\\\d_T = -0.201 \times 10^{-3} + 0.115 \times 10^{-3}-0.402 \times 10^{-3}\\\\d_T = -0.488 \times 10^{-3}\;m\)

Explanation:

Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface.

if a cold worked piece of steel has undergone recrystallization and grain growth, one would expect it to be softer and more ductile than before, with improved toughness and a more uniform microstructure.

When a cold worked piece of steel undergoes recrystallization and grain growth, it typically results in a reduction of the strength and hardness of the material, while increasing its ductility and toughness. This is because recrystallization and grain growth are mechanisms that occur in metals as a result of high temperatures that cause the existing grains to "heal" or "grow" into larger, more uniform grains.Recrystallization occurs when a cold worked piece of steel is heated to a temperature high enough to cause the existing grains to undergo complete recrystallization, forming new and uniform grains that are more evenly distributed throughout the material. This process typically occurs at temperatures between 500-700°C for most steels.Grain growth occurs when the newly formed grains that result from recrystallization continue to grow and increase in size as the temperature is increased further. This process typically occurs at temperatures above 700°C for most steels.As the new grains form and grow, the original deformation structure of the material is largely eliminated, resulting in a loss of strength and hardness. However, the increased uniformity of the grains can also improve the material's ductility and toughness, making it more resistant to fracture and more capable of absorbing energy before failure.

They contain pressurized agents that are specifically formulated to extinguish different types of fires. Freezing temperatures can significantly impair the functionality of fire extinguishers and render them ineffective in emergency situations.

When fire extinguishing equipment freezes, several issues can arise. First, the contents of the extinguisher may expand as they freeze, potentially leading to ruptures or leaks in the container. This can cause the extinguisher to malfunction or become hazardous when used. Second, freezing temperatures can affect the performance of the extinguishing agent itself. Certain agents, such as water-based solutions, can solidify or lose their effectiveness when exposed to extreme cold.

It is crucial to store fire extinguishers in suitable environments that are above freezing temperatures. This ensures that the equipment remains in optimal condition and is ready for immediate use during emergencies.
