Answer:
The diameter of the axle is 5.08 cm.
Explanation:
Given that,
Force = 800 N
Distance = 78.0 m
Suppose we need to find the diameter of the axle be in order to raise the buckets at a steady 2.00 cm/s when it is turning at 7.5 rpm.
We need to calculate the radius of axle
Using formula of linear velocity


Where, v =velocity
r = radius
=angular velocity
Put the value into the formula


We need to calculate the diameter of axle
Using formula of diameter



Hence, The diameter of the axle is 5.08 cm.
