The questions following this statement include: 1. find the tension T in the cable. 2. Find the X and Y components of the force exerted on the beam by the pivot. Please help I understand stresses but I don't understand how tension plays into it.

An amusement park ride consists of a car moving in a vertical circle on the end of a rigid boom of negligible mass. The combined weight of the car and riders is 5.0 kN, and the circle’s radius is 10 m. At the top of the circle, what are the (a) magnitude FB and (b) ...

Just sub some numbers in to make it work. For example... tension/mass (16/.2)=80. So 80 is equal to rv^2. so make v=10 m/s and r =.8 m so everything will work out. It stays the same throughout so you can 'make up' the numbers
