Explanation:

Answer:

r = 1.922 mm

Explanation:

We are given;

Yield stress; σ = 250 MPa = 250 N/mm²

Force; F = 29 KN = 29000 N

Now, formula for yield stress is;

σ = F/A

A = F/σ

Where A is area = πr²

Thus;

r² = 2900/250π

r² = 3.6924

r = √3.6924

r = 1.922 mm

The electric ceiling fan was invented in 1882 by engineer and inventor, Philip Diehl. He had earlier invented an electric sewing machine and adapted the motor from this invention to create the ceiling fan. He called his invention the “Diehl Electric Fan” and it was such a success that he soon had many other people competing with him.

Explanation:

A more efficient sampling rate, in this case, would be 140 Hz.

1. To calculate the amount of memory needed to store all the samples, we need to consider the sampling rate, the duration of the measurements, and the bit depth of the ADC.

Given:

Sampling rate = 12 kHz

Duration = 1 week = 7 days = 7 * 24 hours = 7 * 24 * 60 minutes = 7 * 24 * 60 * 60 seconds

To calculate the number of samples collected, we multiply the sampling rate by the duration:

Number of samples = Sampling rate * Duration

Number of samples = 12,000 samples/second * (7 * 24 * 60 * 60) seconds

Now, to calculate the amount of memory needed to store the samples, we multiply the number of samples by the bit depth of the ADC:

Memory needed = Number of samples * Bit depth

Memory needed = (12,000 samples/second * (7 * 24 * 60 * 60) seconds) * 12 bits

2. If we have effectively made the signal band-limited and can guarantee that all the signal content is below 70 Hz, we can apply the Nyquist-Shannon sampling theorem to determine the minimum sampling rate required to avoid aliasing.

According to the Nyquist-Shannon theorem, the minimum sampling rate should be at least twice the highest frequency component in the signal. In this case, the highest frequency component is 70 Hz.

Minimum sampling rate = 2 * highest frequency component

Minimum sampling rate = 2 * 70 Hz

Minimum sampling rate = 140 Hz

Therefore, a more efficient sampling rate in this case would be 140 Hz.

Explanation:

It can only survive outside of the body for six days

A 5 m depth in an open s'ils offiqjuid has a gage pressure of 75 kpa. which weights are specific P1/P2 = H1/H2 and P2 = H2*P1 P2=48*9/3=144kpa as a result.

When you fret about meeting your self or other people's expectations, you feel pressure. Additionally, you could experience it when circumstances are beyond your control and when you lack the time or resources to fulfill obligations.

Briefing

pressure density =p

The Gage pressure (P1)=48kpa

The height (h1)=3m

The Gage pressure (P2)=?

The height (h2)=9m

P=p * g * h

P1/P2=p * g * h1/p * g * h2

Cancelling out similar terms:

Therefore, P1/P2=h1/h2

P2=P1*h2/h1

Hence, P2=48*9/3=144kpa.

The only process I can think of that would satisfy the conservation of energy principle but does not occur in nature is a perpetual motion machine.

Perpetual Motion Machine would produce work indefinitely without any external input of energy, thus violating the first law of thermodynamics which states that energy cannot be created or destroyed, only converted from one form to another.

While it is theoretically possible to design a machine that appears to produce more energy than it consumes, such a machine cannot exist in reality due to the various energy losses that occur in any real-world system.

These losses can occur due to factors such as friction, heat transfer, and resistance in electrical circuits, among others.

When two loads are not likely to be used at the same time, only the load is permitted to be used in the load calculation is called  the diversity factor or demand factor.

If two things won't be used at the same time, it's okay to only think about the one that will be used for the calculation.

In electrical engineering and the design of power systems, the diversity factor is a measure of how much the combined maximum demands of different loads vary compared to the overall maximum demand on the power system. This considers the idea that not all loads are always working at their highest level at the same time.

Explanation:

The Formula for Froude Number is given as follows:

Froude No. = Inertial Forces/Gravity Forces

Froude No. = v/√(gD)

where,

v = velocity = 1 m/s

g = 9.8 m/s²

D = Depth of channel = 3 m

Therefore,

Froude No. = (1 m/s)/√[(9.8 m/s²)(3 m)]

Froude No. = 0.18

hence, the correct option will be:

Answer:

The force needed to lift a 500 newton-load is 125 newtons.

The mechanical advantage of the lever is 4.

Explanation:

Needed force is equal to the weight of the load. The Law of Lever, which is a particular case of the definition of Torque, states that force is inversely proportional to distance from fulcrum, that is:

\(F_{F} \cdot r_{F} = F_{L}\cdot r_{L}\) (1)

Where:

\(F_{F}\) - Needed force, in newtons.

\(r_{F}\) - Force arm, in meters.

\(F_{L}\) - Load force, in newtons.

\(r_{L}\) - Load arm. in meters.

The mechanical advantage of the lever (\(n\)), no unit, is determined by following formula:

\(n = \frac{F_{F}}{F_{L}}\) (2)

If we know that \(F_{F} = 500\,N\), \(r_{F} = 2\,m\) and \(r_{L} = 8\,m\), then the load force needed to lift is:

\(F_{L} = F_{F} \cdot \left(\frac{r_{F}}{r_{L}} \right)\)

\(F_{L} = 125\,N\)

The force needed to lift a 500 newton-load is 125 newtons.

And the mechanical advantage of the lever is:

\(n = 4\)

The mechanical advantage of the lever is 4.

P2 = 600 kPa

T1 = 277°c  = 550 k

Table used : Table ( A - 17 ) Ideal gas properties of air

a) determining the isentropic efficiency of the compressor

Л = ( h2s - h1 ) / ( h2a -  h1 ) ---- ( 1 )

where ; h1 = 300.19 kJ/kg , T1 = 300 K , h2a = 554.74 kJ/kg , T2 = 550 k

To get h2s we have to calculate the the value of Pr2 using Pr1(relative pressure)

 Pr2 = P2/P1 * Pr = ( 600 / 95 ) * 1.306  hence; h2s = 500.72 kJ/kg

A V-8 engine that posses a firing order of 18436572 with number 1 cylinder on compression, the cylinder which would be on the exhaust stroke is number: A. 6.

An injector can be defined as a mechanical device that is designed and developed for the introduction of fuel into the internal combustion system of an engine, especially under pressure.

In Engineering, there are two (2) main types of fuel injection system and these include the following:

A sequential fuel injection is typically designed and developed to spray fuel into the internal combustion system of an engine based on the firing order that is configured within it by the manufacturer.

As a general rule, one of the two-paired spark plugs within the internal combustion system of an engine is always designed to have a negative polarity while the other spark plug is designed to have a positive polarity always.

In this context, we can infer and logically deduce that a V-8 engine that posses a firing order of 18436572 with number 1 cylinder on compression, the cylinder which would be on the exhaust stroke is number 6.

Answer:

Potential energy

Explanation:

"Potential energy" is a type of energy an object has when it's at rest or in this case not moving. The car is parked, and the engine is off, that means there is no electrical, kinetic, thermal, or mechanical energy in play since the engine isn't running and the car isn't moving. The radio is off too so that means there is no sound energy or electric energy (again) in play either. You are just parked with the car completely shut off, but you do have the potential to move the car by turning on the engine and start driving, which means potential energy is currently in use.
