1. (30 points) This gear train is similar to that in the assigned project; it has gears 1, 2, 3 and 4. The input is from the pulley (belt transmission) to the shaft Gear 1, n = 2400rpm and the input power is H = 30KW (no power loss). The rotation direction of gear 1 (also shaft 1) is shown. Gear parameters are: m = 5, m3 = 6, N= 26, 2= 81, N3= 27, N = 97, and pressure angles are all 20 degree. The gear centers are O1, 02, 03, and 04. For a = 30 mm, b = 40 mm, c = 40 mm, d= 35 mm, calculate and determine a) The torque transmitted on each gear and forces on each gear, and the forces on each shaft; plot the free-body diagram for each shaft. Note that the force on gear 1 and T are marked already. All forces should be in their correct directions. b) The moment diagrams of each shaft, and the magnitude and location of the maximum bending moment on each shaft. You need to plot the forces and bending moment diagrams in the xz and xy planes.
