A 900 N man, 165 cm tall lies on a center of gravity reaction board with his feet at the left end. The reaction board is 206 cm long, weighs 249.2 N, has a uniform distribution of mass, and is supported at both ends by knife-edges. At the right end the knife-edge rests on a scale which reads585 N. Assuming the CG of the reaction board is 103 cm from A, what percentage of his height is his center of grav
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.

The reaction board is 206 cm long, weighs 249.2 N, has a uniform distribution of mass, and is supported at both ends by knife-edges. At the right end the knife-edge rests on a scale which reads585 N. Assuming the CG of the reaction board is 103 cm from A, what percentage of his height is his center of gravity (measured from his feet?)
