What is the minimum coefficient of friction u between the rope and the fixed shaft which will prevent the unbalanced cylinders from moving? Assume W1 = 49 lb, W2 = 77 lb. W Answer:u=
Question 12 8 pts Block A rests on the ground and the coefficient of static friction between the ground and Block A is 0.20. If the weight of the suspended cylinder D is 5 lb, determine the minimum weight of Block A (in pounds) so that it does not tip. Neglect any friction at pulley C. Round to the nearest whole pound. Hint 1: Break the tension force from the rope into component forces. Hint 2: It might help to...
The drawing shows a circus clown who weighs 890 N. The coefficient of static friction between the clown’s feet and the ground is 0.590. He pulls vertically downward on a rope that passes around three pulleys and is tied around his feet. What is the minimum pulling force that the clown must exert to yank his feet out from under himself?

quick help.
If the coefficient of static friction between the man's shoes and the pole is?-o.55, determine the minimum coefficient of static friction required between the belt and the pole at A in order to support the man. The man has a weight of 175 lb and a center of gravity at G 3.75 ft 2.25 ft 0.75 ft 0.5 ft
9.[1pt] In the Figure, a block m sits on a table. There is static friction between block and table. Block m2 hangs from a knot, as shown. Call the tension in the rope connecting the knot to mi T1". Call the tension in the rope connecting the knot to m2, "T2". Call the tension in the third rope (the one tipped up by an angle theta, connecting the knot to the wall), "T3". The system is in equilibrium Which of...
