A gymnast is attempting to perform splits. From the information given in Figure 9.36, calculate the magnitude and direction of the force exerted on each foot by the floor.
Step 1 of 6</p>
For the given gymnast who is trying to perform splits, we need to calculate the magnitude and direction of the force exerted on the each foot by the floor.
By drawing free body diagram of the gymnast at center of gravity , we can estimates the forces acting on the foot.
Step 2 of 6</p>
The gymnast hips and legs splits enough to support the body weight of her.To draw the free body diagram for the gymnast,
A downward force W acts vertically downward at the center of gravity of the gymnast. Also two leg forces acts on CG, at an angle form the vertical axis along the legs of the gymnast as shown in the FBD above.
Step 3 of 6</p>
Under equilibrium, the net force will be zero.Horizontal components of forces,
Vertical components of forces.
At equilibrium, forces will be balanced
