Textbook Question
Chapter 10, Problem 61GP
A uniform solid cylinder of mass M is supported on a ramp that rises at an angle θ above the horizontal by a wire that is wrapped around its rim and pulls on it tangentially parallel to the ramp (Figure 10.75). (a) Show that there must be friction on the surface for the cylinder to balance this way. (b) Show that the tension in the wire must be equal to the friction force, and find this tension.

A uniform plank of length 5 m and weight 200 N rests horizontally on two supports with 1.1 m of the plank hanging over the right support. To what distance x, can a person who weights 430 N walk on the overhanging part of the plank before it just starts to tip?
What is the net torque around the pivot point (take the FR support as the pivot point)?
A uniform beam of mass 138 kg and length 7 m is pinned at its left end so that it is free to rotate about that end. Its right end rests against a vertical, slippery wall such that the beam makes a 57 degree angle with the horizontal. Calculate the normal force the vertical wall exerts on the beam, in N. Even though the force points to the left your answer should be a positive number.

Explainarrow_forwardOne end of a uniform meter stick is placed against a vertical wall. The other end is held by a lightweight cord that makes an angle theta with the stick. The coefficient of static friction between the end of the meter stick and the wall is 0.400.
