Answer:
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:
[tex]T = m.g = 60\ kg\cdot 9.8\ m/s^2[/tex]
T=588 N
The tension force of the cable is 588 N
