Gymnast Force

Satisfactory Essays
Gravity is pulling the gymnast 20 N down. The force she is putting down on the bar measures to 20 N. The bar is supporting the weight of the gymnast. Its force is 35 N in the upward direction. Friction is another factor, with the force of 5 N up. A gymnast needs friction in order to be able to swing and avoid slipping. Both directions of force even out to 40 N on each side. When you set up an equation and subtract the two directions, the amount of force equals out to 0 N. This ending sum of zero means that the forces are balanced. The balanced force is the reason why the gymnast is not falling off the bar and the bar isn’t collapsing. The bar and friction supply enough force to support the gymnast’s force and gravitational pull.
