A 20-lb block is attached to spring A and connected to spring B by a cord and pulley. The block is held in the position shown with both springs unstretched when the support is removed and the block is released with no initial velocity. Knowing that the constant of each spring is 12 lb/in., determine (a) the velocity of the block after it has moved down 2 in., (b) the maximum velocity achieved by the block. v = 1.638 ft/s Vmax= 1.892 ft/s

Two masses, m1 and m2, are each suspended on identical springs. They were displaced an equal distance from equilibrium position and were released simultaneously. They are both at position of initial displacement at the instant m1 has completed 5 cycles and m2 has completed 3 cycles. m1=3 kilograms, determine the mass of m2 in kg
A simple pendulum is set into motion at two different times with different initial conditions. The first time: the bob is in its equilibrium position and is given an initial velocity +2 m/s. The maximum height reached by the bob is h1,max and the period of motion is T1. The second time: the bob is in its equilibrium position and is given an initial velocity +6 m/s. The maximum height reached by the bob is h2,max and the period of motion is T2. Assume that the motion is simple harmonic, which of the following is true? h2.max=9h,max and T2 37,

A system of blocks is pulled by a force P. The string connecting blocks A and B passes over a pulley whose coefficient of friction between string and pulley is 0.25. The coefficient of friction between surface and blocks is 0.20. Block A weighs 200N and block B weighs 300N. Determine, a. the minimum value of P for impending motion to the right. b. the tension connecting block B. B= 30° В A 30°
Q2) A loaded Porter governor has four links each 200 mm long and are hinged at a distance of 40 mm from the axis of rotation. The mass of each ball is 2 kg and mass of the sleeve is 20 kg. The governor sleeve begins to rise at 300 r.p.m. when the links are at an angle of 35° to the vertical. Assuming the friction force to be constant, determine the minimum and maximum speed of rotation when the inc lination of the arms to the vertical is 40°.
A spring is used to stop a 50-kg package which is moving down a 20° incline. The spring has a constant k =34 kN/m and is held by cables so that it is initially compressed 50 mm. Knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest. Assume that the kinetic coefficient of friction between the package and the incline is 0.2. 2 m/s 50 kg 8m Cable 20° The maximum additional deformation of the spring in bringing the package to rest is 0.574 x m.
Problem 3. The system of two blocks, cable, and frictionless pulley is initially at rest. Determine the minimum magnitude of P necessary to cause motion. For this value of P, what is the magnitude of the tension in the cable? Hint: For the top block to move to the right, the bottom block must simultaneously move to the left since they are connected via the cable. 5 kg Hq=0.35 10 kg H = 0.50
