An inextensible rope passing over a smooth pulley has two blocks of mass 20 kg and 30 kg attached to its two ends. The mass of the pulley is 10kg and radius of gyration 0.3 m. Determine the tension on the rope and the acceleration of the masses.

Two blocks A and B weighs 150 N and 200 N respectively is supported by a flexible cord which passes through a frictionless pulley which is supported by a rod attached to a ceiling. Neglecting the mass and friction of the pulley, compute the acceleration on the blocks and the tension on the rod supporting the frictionless pulley.

Three blocks A, B and C are placed on a horizontal frictionless surface and are connected by chords between A, B and C. Determine the tension between block B and C when a horizontal tensile force is applied at C = 6.5 N. Masses of blocks are A = 1.2 kg, B 2.4 kg, and C = 3.1 kg.

An elevator weighing 2000 lb attains an upward velocity of 16 fps in 4 sec with uniform acceleration. What is the tension in supporting cables?
