Question

3.5m 200kg 75kg 21. The medieval catapult consists of a 200 kg beam with a heavy ballast at one end and a projectile of 75.0 kg at the other end. The pivot is located 0.5 m from the ballast and a force with a downward component of 550 N is applied by prisoners to keep it steady until the commander gives the word to release it. The beam is 4.00 m long and the force is applied 0.900 m from the projectile end. Consider the situation when the beam is perfectly horizontal. a. Draw a free-body diagram labeling all torques b. Find the mass of the ballast c. Find the force on the horizontal support d. How would the angular acceleration change as the beam moves from the horizontal to the vertical position. (Give a qualitative explanation.) a. In order to maximize range at what angle should the projectile be released? b. What additional information and/or calculation would have to be done to determine the range of the projectile?
