Question

A 7.0 m long ladder rests against a vertical wall, with which it makes an angle of 45\deg , and on a floor. If a man, whose weight is one-half of that of the ladder, climbs it, at what distance along the ladder will he be when the ladder is about to slip (by virtual work principle)?

Step 1

The forces include the weight of the ladder (W_l), the weight of the man (W_m), the normal force from the wall (N_w), the normal force from the ground (N_g), and the frictional force (F_f) at the base of the ladder. Show more…
