Rafael Simon · Answer 1

Magnitude of force on each chain = 314.58 N

Explanation:

Refer the given figure to see the arrangement.

We have Vertical force of 100 lb mass downward.

That is mass = 100 lb = 45.35 kg

Weight = 45.35 x 9.81 = 444.88 N

On resolving F, we will have 2Fcos45 in upward direction.

Equating

2Fcos45 = 444.88 N

F = 314.58 N

Magnitude of force on each chain = 314.58 N
