As shown, a frictionless pulley hangs from a system of
springs and a cable. The pulley is equidistant between the two
supports attaching the springs to the ceiling. The distance between
the supports is d=1.50 m . The cable cannot stretch and its length
between the two springs is 1.8 m.

Two slender links, AC and BC, extend from a wall and support a pulley at C. A cable, tied at D, passes over the small pulley at C and experience an 80-lb force at its free end E. If the pulley is frictionless and of negligible determine the forces developed in members AC and BC. An inextensible (cannot stretch) cable AC and spring CB are originally horizontal. A 100-N weight is attached to point C, and the system is...

Problem (3) A motor M and a frictionless pulley-cable system are used to lift the 850 lb crate shown at a constant acceleration. The motor has an efficiency of E = 0.6 and the input power to it is 92 hp at the instant when the load has been hoisted s = 15 ft starting from rest. Determine the tension force in the cable. Neglect the mass of the pulleys and cable.

An object of mass -20 kg is lifted by a standard man with the aid of a pulley, as shown in the figure below. The upper arm is held vertical and the lower arm has an angle of θ·33° with the horizontal. The label c.m. marks the centre of mass of the lower arm. Consider the force due to the weight of the object M, the weight of the lower arm and hand, the tension due to the triceps muscle,...
