The system in the figure is in equilibrium. A concrete block of mass 225 kg hangs from the end of the uniform strut of mass 45.0 kg. A cable runs from the ground, over the top of the strut, and down to the block, holding the block in place. For angles phi=30.0 degree and theta= 45.0 degree,

Find:

(a) the tension T in the cable and the

(b) horizontal components of the force on the strut from the hinge

(c) vertical components of the force on the strut from the hinge.

A block with mass m =6.7 kg is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x = 0.27 m. While at this equilibrium position, the mass is then given an initial push downward at v = 4.5 m/s. The block oscillates on the spring without friction. 1. What is the spring constant of the spring? 2. What is the oscillation frequency? 3. After t = 0.46 s what is the speed of the...
