*Problem 13-16 An engine of mass M1 is suspended from a spreader beam of mass M2 and hoisted by a crane which gives it an acceleration a when it has a velocity v. Determine the force in chains AC and AD during the lift. Problem 13-17 The bullet of mass m is given a velocity due to gas pressure caused by the burning of powder within the chamber of the gun. Assuming this pressure creates a force of F = F 0sin( t / t0) on the bullet, determine the velocity of the bullet at any instant it is in the barrel. What is the bullet"s maximum velocity?
