Question

5) Two cables support a mass of 100kg. One cable is perfectly horizontal, while the other

makes an angle of 40 degrees above the horizontal. Find the tension in the horizontal
cable.

Answer 1

T sin θ = M g = W cable supporting weight

T = 100 * 9.8 / sin 40 = 1525 N

T cos θ = Th horizontal force due to cable

Th = 1525 cos 40 = 1168 N
