A small mass, m = 200 grams, hangs vertically from a thin cable that is attached firmly to the ceiling. The thin cable has negligible mass. Calculate the magnitude of the tension, T, in the cable. Also, state the direction of the tension in the cable. T = 1.96 N, acting downward. T = 19.6 N, acting downward. T = 1.96 N, acting upward. T = 19.6 N, acting upward.

A patient with a broken tibia has the lower half of his leg suspended horizontally by a cable attached to the center of his foot. The tension in the cable needs to exert a force of F, = 25 N horizontally for traction and F, = 30 N vertically upward to support the leg. Find the magnitude of the tension in the cable. Hint: Put the center of the patient's foot at the origin of the xy-plane. Pulley F₂ x F₁ (Give your answer to one decimal place. Use symbolic notation and fractions where needed.) Flension N

Force T pulls at angle a up from the horizontal on a section of pipe of weight W as shown, but the pipe remains motionless. The coefficient of static friction between pipe and floor is µ. We know that the magnitude of the total frictional force on the pipe by the floor is: 1(c T. A) 27 cos a B) µ(W +T sin a) C) µW +T cos a D) T cosa W A B
