(a) Choose the following values. None of them can be 0. Numbers can be picked by expert The length of the ladder The mass of the ladder The inclination of the ladder The height of the hammer. The mass of the hammer. (b) Draw the ladder. (c) Draw all forces acting on the ladder.
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 ladder leans against a wall as shown below. A hammer is placed on one of the rungs (you can assume the hammer is pointlike). The ladder feels a
