Answer:
See below
Step-by-step explanation:
5000 ton = 10 000 000 pounds = 4,535,924 kg
Normal force = mg cos 10
then friction force = .18 * mg cos 10
the force downplane = mg sin 10
the force of the winch + force downplane must be = f of friction
w+ mg sin 10 = .18 mg cos 10
w = mg ( .18 cos 10 - sin 10 ) Plug in the numbers to find
w = 160 957 N
( this converts to 36185 pound-force)
