Machine Design A shaft is subjected to a maximum bending stress of 80 N/mm² and maximum shearing stress equal to 30 N/mm² at a particular section. If the yield point in tension of the material is 280 N/mm² and the maximum shear stress theory of failure is used, then the factor of safety obtained will be 3.5 3.0 2.8 2.5 3.5 3.0 2.8 2.5 ANSWER DOWNLOAD EXAMIANS APP
Machine Design The relation between the pitch of the chain (p) and pitch circle diameter of the sprocket (D) is given by (where T = Number of teeth on the sprocket) p = D sin (360°/T) p = D sin (180°/T) p = D sin (120°/T) p = D sin (90°/T) p = D sin (360°/T) p = D sin (180°/T) p = D sin (120°/T) p = D sin (90°/T) ANSWER DOWNLOAD EXAMIANS APP
