Since the elevator is moving with a constant speed and not accelerating, the tension in the string is simply the normal, routine, everyday boring weight of the object. Since the elevator is moving with a constant speed and not accelerating, the tension in the string is simply the normal, routine, everyday boring weight of the object.
The magnitude of the tension in the string, when the elevator is moving with constant speed is equal to the mass time gravitational force.
What is tension in the string due to hanging weight?
Tension is the pulling force carried by the flexible mediums like ropes, cables and string.Tension in a body due to the weight of the hanging body is the net force acting on the body.
For the body with mass (m) hanging on a string, the tension force of string can be given in three ways,
- 1) The tension in the string when body is at rest or moving with constant velocity- At the rest the tension will be the product of mass time gravitational force. It can be given as,
[tex]T=mg[/tex]
- 2) The tension in the string when body is moving upward-When the body is moving upward, both the gravitational and acceleration force acting on it, and the magnitude of tension will be due to the sum of these two force. It can be given as
[tex]T=m(g+a)[/tex]
- 3) The tension in the string when body is moving downward-When the body is moving downward, difference the gravitational and acceleration force acting on it. It can be given as
[tex]T=m(g-a)[/tex]
Here, in the problem the object is hanging by a string from the ceiling of an elevator and the elevator is moving upward with a constant speed.
As the elevator is moving with constant velocity. Thus, the magnitude of the tension in the string,
[tex]T=mg[/tex]
