(a) calculate the moment at point "c", where point "c" is the square 3'' below the centroid (b) calculate the bending stress at the point "c" at 3 inches below the centroid

(c) given that the shear stress is 22.3 psi, draw a mohr's circle for the stress block

(d) prove the shear stress is 22.3 psi through calculating it

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.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
