Consider a rigid steel beam of length L = 13.5 m and mass mb = 420 kg resting on two supports, one at each end. A worker of mass mw = 61 kg sits on the beam at a distance x from support A. Refer to the figure, though note that it is not drawn to scale. Enter an expression for the force support B must exert on the beam in order for it to remain at rest, in terms of defined quantities, x, and g.
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.
