A uniform, 255-N rod that is 2.00m long carries a 225-N weight at its right end and an unknown weight W toward the left end. When W is placed 50.0cm from the left end of the rod, the system just balances horizontally when the fulcrum is located 75.0cm from the right end. (a) Find W. (b) If W is now moved 25.0cm to the right, how far and in what direction must the fulcrum be moved to restore balance?
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 uniform, 255-N rod that is 2.00m long carries a 225-N weight at its right end and an unknown weight W toward the left end. When W is placed 50.0cm from the left end of the rod, the system just balances horizontally when the fulcrum is located 75.0cm from the
right end.
(a) Find W.
(b) If W is now moved 25.0cm to the right, how far and in what direction must the fulcrum be
moved to restore balance?
