A man sits in a chair that is suspended from arope. The rope passes over a pulley suspended from the ceiling, and the man holds the other end of the rope in his hands.What is the tension in the rope, and what force does the chair exert on the man ?

A block is attached to each end of a rope that passes over a pulley suspended from the ceiling. The blocks have different masses. If the rope does not slip on the pulley, then at any instant after the blocks start moving, the rope

A man of mass m stands on a frame of mass M. He pulls on a light rope, which passes over a pulley. The other end of the rope is attached to the frame. For the system to be in equilibrium, what force must the man exert on the rope?

A man with mass 85 kg stands on a platform with mass 25 kg. He pulls on the free end of a rope that runs over a pulley on the ceiling and has its other end fastened to the platform. The mass of the rope and the mass of the pulley can be neglected, and the pulley is frictionless. With what force does he have to pull so that he and the platform have an upward acceleration of 2.2m/s^(2) . (Take g= 10m/s^(2) )

A mass of 3kg is suspended by a rope of length 2m from the ceilling A force of 40N in the horizontal direction is applied atmidpoint P of the rope the as shown. What is the angle the rope makes with the vertical in equilibrium and the tension in part of string attached to the ceiling ? (Neglect the mass of the rope, g =10m//s^(2)) .

A mass of 20 kg is suspended by a rope of length 4 m from the ceiling. A force of 60 N is applied at the midpoint of the rope in the horizontal direction. What is the angle made by the rope with the vertical in equilibrium? Assume that the mass of the rope is negligible and g=10m//s^(2)

A man sits on a chair supported by a rope passing over a frictionless fixed pulley. The man who weighs 1,000N exerts a force of 450N on the chair downwards while pulling the rope on the other side. If the chair weighs 250N then the acceleration of the chair is .

Figure 5-55 shows a man sitting in a bosun's chair that dangles from a mass-less rope, which runs over a massless, frictionless pulley and back down to the man's hand. The combined mass of man and chair is 103.0 kg. With what force magnitude must the man pull on the rope if he is to rise (a) with a constant velocity and (b) with an upward acceleration of 1.30" m"//"s"^(2) ?

Block A of mass m//2 is connected to one end of light rope which passes over a pulley as shown in fig. A man of mass m climbs the other end of rope with a relative acceleration of g//6 with respect to rope. Find the acceleration of block A and tension in the rope.
