The ladder in the picture has a mass of 34 kilograms and a length 3.2 meters. Fn=333.2N a.Assume that the ladder's weight is evenly distributed, so it can be treated as a single force through the middle. If the ladder is at a 69° angle from the ground, what is the torque exerted by the weight (using the floor as the pivot point)? b.The torque from the ladder must be balanced by the torque caused by the normal force on the wall. Calculate this force. c.The normal force from the wall must be balanced by the friction force from the floor. Determine the minimum coefficient of friction to keep the ladder from slipping.
