An engineering component has, at a certain point on its free surface, strains given by = 1.1e-3, = 2.0e-4, and = 5.0e-4. the young’s modulus is 200 gpa and possion’s ratio is 0.33. what tensile yield strength is needed for the material of this component if a safety factor of 3.0 against yielding is required? assume (a) the tresca yield criterion, and (b) the von mises yield criterion. (820 mpa. 710 mpa)

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.
