What is the difference between class 1 and class 3 lever?

Answers

Answer 1
In a Class Three Lever, the Force is between the Load and the Fulcrum. If the Force is closer to the Load, it would be easier to lift and a mechanical advantage. Examples are shovels, fishing rods, human arms and legs, tweezers, and ice tongs. A fishing rod is an example of a Class Three Lever.
Answer 2

Answer:

the class is different and the topic treated in class 1 is different from class 3

1. A flywheel is suspended by resting the inside of the rim on a horizontal knife edge so that the wheel can swing in a vertical plane. The flywheel has a mass of 350Kg. The knife edge is parallel to and making 350mm from the axis of the wheel. The time for making one small oscillation is 1.77 seconds. Assuming that the centre of mass is in the axis of the wheel, determine:
(I).The radius of gyration of the wheel about the axis.
(II). The torque to increase the speed of the flywheel at uniform rate from 240 rev/min to 250 rev/min in 0.75seconds when the flywheel is revolving about its axis.
2. A solid metal cylinder 450mm diameter is suspended with its axis vertical by means of a wire coaxial with the cylinder and rigidly attached to it. The stiffness of the wire is 22Nm per radian of twist. Find the necessary mass of the cylinder so that when it is given a small angular displacement about its axis, it will make 40 vibrations per minute.​

before touching any electrical conductor?
A. Remove all electrical loads from the

B. Check the condition of all circuit
breakers in the load center.
O C. Measure the voltage on the conductor

O D. Consult the NEC.

Answers

Answer:

D. Measure the voltage on the conductor with a known good meter

Explanation:

In a safe approach to electrical work,the thing that you should always do immediately before touching any electrical conductor is  C. Measure the voltage on the conductor with a known good meter.

What should be done immediately before touching any electrical conductor?

One should never touch any wires or conductors until you are certain that their electrical supply has been turned off. Circuits must be locked out and marked with a tag to prevent re-energizing them. A conductor is always risky. Before working on a circuit, always test to make sure it is deenergized.

The action you should always do right away before touching any electrical conductor is  the safest approach to electrical work. Use a reputable meter to measure the voltage across the conductor.

1- The preexponential and activation energy for the diffusion of iron in cobalt are 1.1×10-5 m 2 /s and 253,300 J/mol, respectively. At what temperature will the diffusion coefficient have a value of 2.1×10-5 m 2 /s ?

Answers

The temperature at which the diffusion coefficient have a value of 2.1×10-5 m 2 /s is  -47078 K.

Using the relation;

logD = logDo - Ea/2.303RT

D = diffusion coefficient

Do =  preexponential

Ea = activation energy

R = gas constant

T = temperature

Substituting values;

log(2.1×10-5)= log (1.1×10-5 ) - 253,300/2.303 × 8.314 × T

log(2.1×10-5) -  log (1.1×10-5 ) =  - 253,300/2.303 × 8.314 × T

log[2.1×10-5/1.1×10-5] = - 253,300/2.303 × 8.314 × T

0.281 × (2.303 × 8.314 × T) = - 253,300

Question 2

Sarah was recently promoted to a managerial position at her industrial engineering company. With her new role, she is now responsible for overseeing the company's production factory, meaning approximately 50 factory workers now report to her. Although Sarah previously worked as an engineer and did not have any experience running a factory, she is excited to begin her new position. At the end of her first day, Sarah is confused to see her factory workers continuing to work well past the end of their 8-hour shift. She then goes to the factory supervisor (who reports to her) to express concern because the factory does not have the budget to pay so many workers overtime. The supervisor smiles at Sarah and explains that the factory meets production goals by making the factory workers work off the clock. The workers are well aware of this expectation and went along with it in order to keep their jobs. Sarah is shocked to learn this illegal practice had become part of the company culture, but the supervisor explains that the company's CEO (who is Sarah's boss) is well aware of this expectation.

What shouldSarah do ? (15)​

Answers

Analyzing the information from the case above, the ideal would be Sarah to schedule a meeting with your boss to expose the facts and seek a solution, as this is an ethical dilemma that she became aware of and as a new manager she will have to deal with it.

She became aware of an illegal practice that has become part of the company's culture and that her boss is aware of this illegality.

Sarah needs to be aware that her talk about the possibility of changing company policy and complying with ethics could jeopardize her job.

But on the other hand, if Sarah's boss does not accept to change the company's ethical parameters, she will also be running the risk of being part of this illegal act and damaging her reputation.

Therefore, the best option for Sarah is to be honest and talk to her boss about the situation.

In this way, it can help workers receive their rights, if their argument is accepted, and transform the company into an ethical place with a culture focused on the development and compliance with ethics and legislation.
