Explanation:
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.
Reached equilibrium, the positive and negative charges cancel or balance each other out.
