A ladder of weight 600 N and length 10.0 m is placed against a smooth vertical wall. A person weighing 1000 N stands on the ladder 6.0 m from the bottom as measured along the ladder. At a height of 7.0 m the ladder is on the point of slipping. Find: (a) Calculate the force exerted by the wall. (b) Calculate the normal force exerted by the floor on the ladder. (c) The force of friction between the floor and ladder. (d) Calculate the coefficient of static friction if the ladder is on the point of slipping when the person is 8.0 m up 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.
