two circular rods of 50mm diameter are connected by a knuckle joint as shown below, by a pin of 40mm in diameter. if a pull of 120KN acts at each end, find the tensile stress in the rod and shear stress in the pin.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
