What should be the angle between the cable and the box

Reference no: EM13496002

A box of sand, initially at rest, is to be pulled across a floor by means of a cable in which the tension cannot be allowed to exceed 1100N. The coefficient of static friction between the box and the floor is 0.35.

What should be the angle between the cable and the box in order to pull the greatest mass of sand?
