- 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.arrow_forwardA 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.)

The feeder is supported by a vertical string, which is in turn tied to two strings, each of which is attached to a horizontal branch. The left string makes a 60° angle with the branch, while the right string makes a 30° angle. What is the tension in each string (in N)? left string __N right string __N bottom string __Narrow_forward

The maximum permissible mass of each car with occupants is 2200 kg. The cars, riding on a support cable, are pulled by a second cable attached to the support tower on each car. Assume that the cables are taut and inclined at angle 0 = 39º. What is the difference in tension between adjacent sections of pull cable if the cars are at the maximum permissible mass and are being accelerated up the incline at 0.85 m/s²?
