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 3.5 2.8 2.5 3 3.5 2.8 2.5 ANSWER DOWNLOAD EXAMIANS APP
Machine Design Two rigid plates are clamped by means of bolt and nut with an initial force F. After tightening, a separating force P (P < F) is applied to the lower plate, which in turn acts on the nut. The tension in the both after this is F + P F.P P F F + P F.P P F ANSWER DOWNLOAD EXAMIANS APP
