Question

By using a wheel-and-axle arrangement,you can:

• A. magnify the speed
• B. magnify force
• C. effort can be moved through a greater distance by attaching a handle
• D. all of the above

Answer 1

The correct option is D all of the above

$\text{Solution}:$

1. The wheel and axle is a machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other.

2. The wheel and axle can be viewed as a version of the lever, with a drive force applied tangentially to the perimeter of the wheel and a load force applied to the axle, respectively, that are balanced around the hinge which is the fulcrum.

3. By using wheel and axle arrangement speed, force can be magnified as well as effort can be moved through a greater distance by attaching a handle.

$\text{Hence D is the correct optiom}$
