Q.1. (50 pts.): A five-strand NO. 40 roller chain is being proposed to transmit power from a 21 tooth driving sprocket "Q" that rotates at 1200 rpm. The driven sprocket "B" is to rotate at 25% of the speed of the driving sprocket; both sprockets will have uniform rotation. Then: (a) Determine the allowable horsepower that can be transmitted by this sprocket-chain drive. (b) Determine the expected tension "P" in the chain. (c) Calculate the maximum output torque T in shaft "EG. (d) Calculate the rotational speed of shaft "EG". (e) If shaft "EG" is made of steel having yield strength = 45 kpsi, ultimate strength of 70 kpsi and a fully corrected endurance limit Se = 24 kpsi, then find the factor of safety of the shaft using DE-Soderberg method, neglect any possible stress concentration in the shaft. Note that the gears pressure angle is 20, number of teeth of gear C is 40 teeth, and of gear F is 20 teeth. 3 in 3 in, 1.25 in dia. 3 in 10 in 5 in View a-a M 15 in Q.1.
