    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
