A pencil rests against a corner, as shown in the figure. The sharpened end of the pencil touches the wall (no friction) with and the eraser end touches a rough (with friction) horizontal floor. The center of mass of the pencil is located 9.0 cm from the tip of the eraser and 11.0 cm from the tip of the pencil lead. Inclined angle ? = 32degree . Mass of the pencil is 55.0 gram.

(a) Draw a free-body-diagram to show all the forces acts on the pencil? (b) Find the normal force acting on the pencil from the wall? (c) Find the normal and friction forces acting on the pencil from the floor?

An 20 kg plank leans on a rough floor, against a frictionless wall, making an angle of 40 degrees with the horizontal. An 7 kg mass hangs down at a distance of 7 meters from the top end of the plank. Determine all the forces (direction and magnitude) acting on the plank, assuming the plank is in both rotational and also translational (linear) equilibrium, then determine the implied value of the coefficient of static friction of the floor against the...
