Unformatted text preview: m, located equal distances from the center of the plank. If this person tries to stand on the one end of the plank. If the plank is to remain at rest, how massive can he be? Example 11.3) A person with weight 800N climbs a ladder that is 5.0 m long and weighs 180 N. He stops a third way from the bottom of the ladder. a) Find the normal and friction forces on the ladder at its base b) Find the minimum coefficient of static friction needed to prevent slipping at the base c) Find the magnitude and the direction of the contact force on ladder at the base. Problem 11.14) The horizontal beam weighs 150 N. Find a) the tension in the cable b) the horizontal and vertical component of the force exerted on the beam at the wall. Problem 11.13) Find the tension T and the magnitude and direction of the force exerted on the strut by the pivot. Let w be the weight of the grate and that of the strut...
