Answer:
B. 5000
Step-by-step explanation:
The tow rope should be strong enough so that it can overcome the frictional force and pull pallet without breaking. In question following data is given:
Weight of pallet = W = 6000lbs
Coefficient of friction = uK = 0.42
The tow rope required to pull pallet = (Weight of pallet) (Coefficient of friction)
= (W)( uK)
= (6000)(0.42)
= 2520 lbs
5000lbs is higher value than 2520lbs. Hence, if we will use 5000lbs tow rope it can easily pull the pallet.
