A crane is lifting a 60 kg load at a constant velocity. Determine the tension force in the cable.

The tension force of the cable is 588 N

Explanation:

Net Force

The Second Newton's law establishes that the acceleration an object has depends on the net force through the equation:

F = m.a

If the net force is zero, then the acceleration is zero, and the object's velocity remains constant.

The crane lifts a 60 Kg load at a constant velocity. It means the net force acting on the load is zero.

There are two forces acting on the load: The weight of the load and the tension of the cable that holds it.

Since the net force is zero, both forces have the same magnitude:

T=588 N

The tension force of the cable is 588 N

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
