Acylindrical bar that has its lateral surface constrained so that there can be no lateral expansion is then loaded with an axial compressive stress σ . (a) find σ22 and ơ33 in terms of σ and the poissons ratio v, and (b) show that the effective young's modulus eeff = σ11/€11 is given by eeff = (1-v)/(1-20-202)

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.

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
