Reference no: EM13495041

A painter wishes to know whether or not he can safely stand on aladder. The ladder has a mass M1 = 5.0 kg which isuniformly distributed throughout its length L = 6 m. The ladderis propped up at an angle ? = 71°. The coefficient ofstatic friction between the ground and the ladder is µ =0.288, and the wall against which the ladder is resting isfrictionless.

Calculate the maximum mass of the painter for which the ladder willremain stable when he climbs a distance d = 5.2 m up the ladder.

If the painter does not stand on the ladder,what is the minimum angle ? for which the ladder will remainstable?
