You are working for a startup robotics company designing a small differential-drive mobile robot, and your job is to choose the motors and gearing. A diff-drive robot has two wheels, each driven directly by its own motor, as well as a caster wheel or two for balance. Your design specifications say that the robot should be capable of continuously climbing a 20° slope at 20 cm/s. To simplify the problem, assume that the mass of the whole robot, including motor amplifiers, motors, and gearing, will be 2 kg, regardless of the motors and gearing you choose. Further assume that the robot must overcome a viscous damping force of (10 Ns/m) xv when it moves forward at a constant velocity v. regardless of the slope. The radius of the wheels has already been chosen to be 4 cm, and you can assume they never slip. If you need to make other assumptions to complete the problem, clearly state them. You will choose among the 15 V motors in Table 25.1, as well as gearheads with G= 1, 10, 20, 50, or 100. Assume the gearing efficiency n for G=1 is 100%, and for the others, 75%. (Do not combine gearheads! You get to use only one.) a. Provide a list of all combinations of motor and gearhead that satisfy the specifications, and explain your reasoning. (There are 20 possible combinations: four motors and five gearheads.) "Satisfy the specifications" means that the motor and gearhead can provide at least what is required by the specifications. Remember that each motor only needs to provide half of the total force needed, since there are two wheels. b. To optimize your design, you decide to use the motor with the lowest power rating. since it is the least expensive. You also decide to use the lowest gear ratio that works with this motor. (Even though we are not modeling it, a lower gear ratio likely means higher efficiency, less backlash, less mass in a smaller package, a higher top-end speed (though lower top-end torque), and lower cost.) Which motor and gearing do you choose? c. Instead of optimizing the cost, you decide to optimize the power efficiency-the motor and gearing combination that uses the least electrical power when climbing up the 20° slope at a constant 20 cm/s. This is in recognition that battery life is very important to your customers. Which motor and gearhead do you choose? Gearing and Motor Sizing 437 d. Forget about your previous answers, satisfying the specifications, or the limited set of gear ratios. If the motor you choose has rotor inertia J. half of the mass of the robot (including the motors and gearheads) is M. and the mass of the wheels is negligible, what gear ratio would you choose to achieve inertia matching? If you need to make other assumptions to complete the problem, clearly state them.

The two failure theories are the Maximum Principal Stress Theory and the Maximum Shear Stress Theory.

The Maximum Principal Stress Theory states that failure occurs when the maximum principal stress in a material exceeds its ultimate strength.

Failure Criterion for 2D Elements:σ₁ > σ_ult

Failure Criterion for 3D Elements:σ₁ > σ_ult

The individual yield surface for the Maximum Principal Stress Theory is a circle in the principal stress space, centered at the origin with a radius equal to the ultimate strength of the material.

The Maximum Shear Stress Theory states that failure occurs when the maximum shear stress in a material exceeds its ultimate strength.

Failure Criterion for 2D Elements:τ_max > τ_ult

Failure Criterion for 3D Elements:τ_max > τ_ult

The individual yield surface for the Maximum Shear Stress Theory is an ellipse in the shear stress space, centered at the origin with semi-major and semi-minor axes equal to the ultimate shear strength of the material.

The combined yield surface for both theories can be obtained by superimposing the individual yield surfaces. It represents the region of stress states where failure is predicted by either theory.

Crystalline and amorphous materials are two distinct classes of materials in terms of their thermal behavior and atomic arrangement.

a) Thermal behavior:

Crystalline materials have a well-defined and regular arrangement of atoms in a repeating pattern, which gives rise to their ordered atomic structure. As a result, crystalline materials have a characteristic melting point, where the atoms break free from their ordered structure and become disordered as the material transitions from solid to liquid state. In contrast, amorphous materials do not have a well-defined atomic arrangement and do not have a distinct melting point. Instead, they gradually soften and flow as the temperature increases, without undergoing a sharp phase transition.

b) Atomic arrangement:

Crystalline materials have a highly ordered arrangement of atoms, where the atoms are arranged in a regular pattern that repeats in all directions. This ordered structure gives rise to many of the characteristic properties of crystalline materials, such as their mechanical strength, optical properties, and electrical conductivity. In contrast, amorphous materials have a disordered atomic arrangement, where the atoms are arranged randomly without any repeating pattern. This lack of long-range order in amorphous materials gives rise to their unique properties, such as their flexibility, transparency, and lack of cleavage planes.

In summary, crystalline and amorphous materials differ in their thermal behavior and atomic arrangement. Crystalline materials have a well-defined atomic arrangement and a distinct melting point, while amorphous materials have a disordered atomic arrangement and do not have a well-defined melting point. Understanding the differences between these two classes of materials is important in engineering and materials science, as it can help to predict and control their properties and behavior.

Answer:

98 x 100=9,00

Explanation:

To find the value of the average signal power required for a power outage probability of 0.01 for a threshold of p0 = -80dBm, we need to use the Rayleigh fading model, which describes the statistical distribution of signal strength in a wireless communication channel.

The Rayleigh fading model assumes that the magnitude of the received signal power follows a Rayleigh distribution, which is a continuous probability distribution with a scale parameter σ. The probability density function of the Rayleigh distribution is given by:

f(x) = (x/σ^2) * exp(-x^2/(2σ^2))

where x is the signal power, and σ is the scale parameter, which is related to the average signal power P as follows:

σ = sqrt(P/2)

The power outage probability for a given threshold p0 is given by:

Pout = exp(-2*(p0/P))

where Pout is the power outage probability.

Answer:

M/A = 0.425 g/cm²

Explanation:

Given the following data;

Mass = 192 grams

Dimensions = 7 * 10 inches.

To find the mass per unit area;

First of all, we would determine the area of the lead sheet;

Area = 7 * 10

Area = 70 in²

Conversion:

1 square inch = 6.452 square centimeters

70  inches = 70 * 6.452 = 451.64 square centimeters

Next, we find the mass per unit area;

M/A = 192/451.64

M/A = 0.425 g/cm²

Answer:

Explanation:

It appears that you are trying to solve a problem involving an insulated rigid tank containing saturated liquid water and water vapor. To determine the volume of the tank, you will need to know the mass of the liquid water and the mass of the water vapor. The mass of the liquid water can be calculated by multiplying the mass of the water and vapor mixture by the fraction of the mixture that is liquid water (1.4 kg * 0.25 = 0.35 kg). The mass of the water vapor can be calculated by subtracting the mass of the liquid water from the total mass of the mixture (1.4 kg - 0.35 kg = 1.05 kg).

To determine the final temperature of the tank, you will need to know the amount of heat added to the tank by the electric resistor and the specific heat capacity of the water and water vapor mixture. The specific heat capacity is a measure of the amount of heat required to raise the temperature of a substance by a certain amount. The specific heat capacity of water is 4.186 J/g°C, and the specific heat capacity of water vapor is 2.080 J/g°C.

To determine the electric power rating of the resistor, you will need to know the amount of heat added to the tank by the resistor and the time over which the heat was added. The power rating of the resistor is equal to the amount of heat added to the tank divided by the time over which the heat was added.

I hope this helps clarify the problem and provide some guidance on how to solve it. If you have any further questions or need additional help, please don't hesitate to ask.

On-site oil storage containers must be marked “Used Oil.” is the true statement.

Steel containers have long been used to hold oils and other liquids, but regular steel is known to rust, corrode, and degrade more quickly than stronger materials. A stainless steel container offers more protection, and storing oil in one won't result in rust problems.

Use of glass or metal containers is their greatest option. If a person plan to store something in the refrigerator, use containers that can handle the cold. No matter what kind of oil you have, you must keep it away from light. Always keep them out of the way, covered, and away from direct light. The oil should be kept in a cool, dark location, like your pantry. Keep it away from the light and the stove. The oil will oxidize more quickly in the presence of heat and light.

The electromagnet in a DC motor needs to change polarity to ensure that the motor rotates continuously in one direction.

A DC motor works on the principle of electromagnetism, where the interaction between the magnetic fields generated by a permanent magnet and an electromagnet causes the motor shaft to rotate.

The electromagnet is powered by a DC current, which causes it to produce a magnetic field that interacts with the magnetic field of the permanent magnet.

To ensure that the motor shaft continues to rotate in one direction, the polarity of the electromagnet needs to change as the shaft turns, so that the interaction between the two magnetic fields remains in the same direction.

This is achieved by using a commutator, which reverses the current direction in the electromagnet every half turn of the motor shaft, thus changing its polarity and allowing for continuous rotation.

True, it is generally true that it takes less gas to restart a vehicle than it does to let it idle for one minute.

The amount of gas used while idling varies depending on several factors, including the size of the engine, the age of the vehicle, and the outside temperature. However, most experts agree that idling for more than 10 seconds uses more fuel than restarting the engine.

Restarting a vehicle uses a small amount of gas, typically about 10 seconds' worth. This is because modern vehicles are designed with fuel injection systems that use electronic sensors to adjust the fuel-to-air ratio, which means that very little fuel is used during the initial startup.

There are also environmental benefits to turning off the engine instead of idling. Idling for extended periods can contribute to air pollution and greenhouse gas emissions, as well as wear and tear on the engine.
