The piston C moves vertically between the two smooth walls. If the spring has a stiffness of k = 12 lb/in, and is unstretched when θ = 0°, determine the couple M that must be applied to AB to hold the mechanism in equilibrium when θ = 20°.   PLEASE ANSWER CORRECTLY TYPE

The weightless bars AB and CE, together with the 5-lb weight BE, form a parallelogram linkage. The ideal spring attached to D has a free length of 2 in. and a stiffness of 7.5 lb/in. Find the two equilibrium positions that are in the range 0/2, and determine their stability. Neglect the weight of slider F.

The 1200-lb homogeneous block is placed on rollers and pushed up the 10 incline at constant speed. Determine the force P and the roller reactions at A and B.

Both pulleys are fixed to the shaft and as the shaft turns with constant angular velocity, the power of pulley A is transmitted to pulley B. Determine the horizontal tension T in the belt on pulley B and the x, y, z components ofreaction at the journal bearing C and thrust bearing D if θ = 0°. The bearings are in proper alignment and exert only force reactions on the shaft.
