Astudent wants to lift a 350 n bucket of water up from the bottom of a well using a wheel and axle. the wheel has a radius of 55 cm, and the axle has a radius of 15 cm. how much force will the student need to provide to the wheel to turn it and lift the bucket? 28.8 n 4242 n 1283 n 95.5 n

Answer is D - 95.5 N.

Explanation:

First calculate the ideal mechanical advantage (IMA) of the system:

IMA = R/r

IMA = 55/15

IMA = 11/3

This is the factor by which the applied force is reduced. This is how you get a mechanical advantage - you exert less force to accomplish the same thing. In this case:

350 / (11/3) = 95.5 N

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
