This Tension equation is used to compute the tension(T) in a string that is suspending a mass(m) below it.
INSTRUCTIONS: Choose units and enter the following:
Tension(T): The equation returns the tension(T) of a string in Newtons. However, this can be automatically converted to other force units via the pull-down menu.
Tension tells us how much force is being applied to a pulling medium such as a rope. An elementary equation tell us that Tension can be calculated between the relationship of mass, gravity and acceleration:
where:
If the mass is moving upwards then you should list your acceleration as a negative force since the force of gravity is counted as being positive.
