Formula for Tension
The formula of tension in the string or the rope attached to a body is discussed below,
- T = W + ma [When body is travelling upward]
- T = W – ma [When body is travelling downward]
- T = W [When tension is equivalent to body weight]
where,
- T is Tension Force
- W is Weight of the body, (W = mg)
- a is acceleration
- m is mass
Unit and Dimension of Tension Force
As tension is a force as well, it has the same unit and dimension as a force. The si unit of Tension force is Newton(N) which can also be represented by Kgms-2. Other than Newton, in the CGS system dyne is also a unit of tension force.
The dimension of Tension Force is [M1L1T-2] where [M], [L], and [T] are the dimensions of mass, length, and time respectively.
Tension Formula
Tension Force is the type of force from one of the many forces that exist in nature which we humans have defined. Any form of Pull or push of an object is considered a force and for an interaction between two objects, there is always a force acting on each object. It is the external agent which is capable of changing the state of rest or motion of a particular object. Tension Force is transmitted through the rope or chain when they were pulled from either end or both ends together, it helps out in balance with the other forces in the system of containing ropes and chains.
