(2) The 100 lb uniform bar is pinned at O andsupported by a roller at A. A downward 150 lb forceand a moment M are applied at its lower end asshown. (a) If M = 2000 lb-in, determine themagnitude of the reaction force at pin O. (b)Determine the maximum moment Mmax for the bar tobe in static equilibrium.Ans: (a) 522 lb (b) 5000 lb-inM50"4150 lb10"4·5"

Solution:a) If M = 2000 lb-in, Magnitude of reaction at pin O:C + ΣM0 = 0-2000 + 150 * cosθ (50 -…

A 68 kg skydiver jumps out of an airplane. We assume that the forces acting on the body are the force of gravity and a retarding force of air resistance with direction opposite to the direction of motion and with magnitude cv² where c = 0.175 kg and v(t) is the velocity of the skydiver at time t (and upward is positive velocity). The gravitational constant is g = 9.8m/s². m a) Find a differential equation for the velocity v : dv dt b) Determine the terminal velocity in meters per second for free-fall (no parachute). terminal velocity= m/s Note: Answer should be negative for downward velocity.
