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.
Answer:
200.048 kg
Explanation:
Total Black dirt loaded in the pickup (A) = 260.5 kg = 260.500 kg
Quantity of the dirt that blew away (B )= 60452 g = 60.452 kg
Remaining quantity of the black dirt is
Thus, the amount of black dirt the man has when he reaches home = 200.048 kg.
