Question

Take moment at A to find the value of N1 If f = 0.2 at the wall, find the coefficient of friction at the floor. Find the value of N2 in terms of Y or V. If f = 0.2 at the wall, find the coefficient of friction at the floor. Find the value of f in terms of X or H.

A 25 kg ladder, 4m long, rest on a rough
floor and against a vertical wall. The
ladder makes an angle of 350 with the
horizontal as shown. It starts to slip
when a man weighing 75 kg has
climbed half way up. If f = 0.2 at the
wall, find the coefficient of friction at
