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.

An object of mass kg and weight N can be supported by the following combination of tensions and angles of cables:
Tension =N, =degrees
Tension =N, Horizontal
 You may explore the effect of changing the angle upon the required tensions in the cables. Making the angle smaller will increase the required tensions. Why is that?
