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

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
