Equilibrium with torques on a ladder
A uniform ladder, length L= 4.5 m, and having mass M= 36 kg, leans against a frictionless wall with angle c= 50° above the floor. The coefficient of friction between ladder and floor is f=.55. A man whose weight is W= 480 newtons, climbs the ladder. Find the maximum distance d, that he can climb until the ladder slides down.
See problem attachment for picture.
Solution and explanation
Before writing equations, you should show arrows on the diagram for all existing forces on the ladder, including Mg, W, the normal force N and the friction force fN at floor contact, and the force H exerted by the wall on the ladder (horizontally since the ...
