11ft 3ft 4ft Tips: .Neglect the weight of the beams. . Draw 2 FBDs, one for each beam. beam problems, and then combine the resulting equations to solve for the rope tension at A. The force in the rope is always in tension (can't push with a rope). . 17.5ft 2.5ft
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.
A 145lb engineering student who is standing on beam EDF pulls vertically downward on a rope attached to
beam ABC. A second rope is attached vertically between points C and D. If the alligator weighs 985lbs and the
center of gravity of the alligator (the place where the weight can be lumped) is 3ft to the left of the pinned
connection at point B, then what is the pulling force of the student?
