Question

For exam
An uniform ladder 5m long rests on a horizontal ground floor and leans against a smooth vertical wall at angle of 60 with the horizontal. The weight of the ladder is 900N acts at the middle. The ladder is at the point of sliding, when a man weighing 750N stands on a rung 1.5m from the bottom of the ladder. Calculate the coefficient of friction between the ladder and the floor​

Answer 1

Answer:

A ladder 5m long rests on a horizontal ground and leans against a smooth vertical wall at an angle 70° with the horizontal. The weight of the ladder is 900N and acts at its middle. The ladder is at the point of sliding, when a man weighing 750N stands 1.5m from the bottom of the ladder. Calculate coefficient of friction between the ladder and the floor.Read more on Sarthaks.com - https://www.sarthaks.com/509657/ladder-long-rests-horizontal-ground-leans-against-smooth-vertical-wall-angle-horizontal
