The man has a mass of 75 kg, and the beam has a mass of 40 kg. The beam is in equilibrium with the man standing at the end and pulling on the cable. Determine the force exerted on the cable by the man and the reactions at pinned support C.
A particle which moves with curvilinear motion has coordinates in meters which vary with time t in seconds according to x = 3.3t2 + 3.1t - 5.3 and y = 5.1t - 4.0. Determine the coordinates of the center of curvature C at time t = 1.9 s.
Air (an ideal gas) enters an adiabatic nozzle at 3 bar and 38 C and exits at 1 bar and -0.78 C. The process is steady. If the velocity at the inlet is 1 m/s, determine the exit velocity and the ratio of the exit area to the inlet area.
Two identical pool balls of 57.15 mm diameter may move freely on a pool table. Ball B is at rest and ball A has an initial velocity v=v0i. (a) knowing that b=50 mm and e=0.7, determine the velocity of each ball after impact.
