A uniform stationary ladder of length L and mass M leans against a smooth vertical wall, while its bottom legs rest on a rough horizontal floor. The coefficient of static friction between floor and ladder is μ. The ladder makes an angle θ with respect to the floor. A painter of mass 1/2M stands on the ladder a distance d from its base. What's the largest value for d in centimeters, so the ladder won't slip? Assume the ladder is 4.5 m long, the coefficient of friction is 0.54, the ladder is at an angle of 46°, and the ladder has a mass of 85 kg.
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.
