Determine the location(s) where the shear stress is 0 (if they exist, the beam will be in pure bending at those points - if they do not, check the points where the shear stress crosses the 0 axis) and calculate the maximum normal stress. you may assume the beam has a rectangular cross section with height 14 cm and width 10 cm.

On a average work day more than work place firs are reorted

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.
