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 2.8 3.5 3.0 2.5 2.8 3.5 3.0 2.5 ANSWER DOWNLOAD EXAMIANS APP
