7. A torque T = 100 N·m is applied to the shaft EFG. Gear F transmits torque to shaft ABCD through gear C, which drives the chain sprocket at B, transmitting a force P. The sprocket B, gear C, and gear F have pitch diameters of a = 150, b = 250, and c = 125 mm, respectively. The contact force between the gears is transmitted through the pressure angle of 20°. The bearings at A, D, E, and G are simple supports. (15' in total) (1) Determine the tangential and radial forces that the gear F exerts on the gear C. (2) Determine the torque on gear C and sprocket B and determine the force P. (3) Determine the bending moment at the point B and C./nB d = 30 mm -f=250 mm e = 75 mm E a g= 125 mm Y Schematic Figure for Problem #7 T = 100 N.m c = 125 mm x P a = 150 mm View a-a b=250 mm
