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.

Energy conservation with conservative forces: A very small 100-g object is attached to one end of a massless 10-cm rod that is pivoted without friction about the opposite end. The rod is held vertical, with the object at the top, and released, allowing the rod to swing. What is the speed of the object at the instant that the rod is horizontal? 1.8 m/s 1.4 m/s 0.71 m/s 2.8 m/s 4.0 m/s fbb
Ed, Edd and Eddy love to play on a seesaw. It consists of a 1-kg board with a length of 8 meters. One day, the other end broke down. They had to cut it by a meter and maintain the pin support in its original position. Then, they tried the seesaw altogether. Ed (m = 55kg) sat on one side about 3m from the pin while Edd (m = 40kg) and Eddy (m = 40kg) on the other side. If Edd was about 3m as well from the pin, calculate the following: The manitude of the reaction force (N) exerted by the pin support on the board. Assume Eddy is in between Ed and Edd. (mass of board = 1kg)

1. in the figure, a solid 0.2 kg ball with radius 0.4 m rolls smoothly along a horizontal frictionless plank with linear velocity of 4 m/s before elastically colliding with another solid ball of mass 0.1 kg standing at rest on the top of the ramp at height H = 7 m. After the collision 0.1 kg ball rolls smoothly down the ramp until it reaches the horizontal section at the end of the track, at height h = 2 m, and flies off the ramp. What will be the velocity of the second ball just before it flies off the ramp? %3D
