Force Equilibrium Example

Force equilibrium problems like this can be analyzed by drawing a free body diagram of the point of attachment of the mass m, since it must be at equilibrium. The tensions should be resolved into horizontal and vertical components to apply the force equilibrium condition.

If an object of mass kg and weight N is suspended from a rope, it will require a force F = N to pull the suspended mass out to an angle of degrees with the vertical. This will result in a tension of T = N in the rope, compared to a tension equal to the weight of the mass when it is hanging vertically.
