Machine Design A shaft is subjected to fluctuating loads for which the normal torque (T) and bending moment (M) are 1000 N-m and 500 N-m respectively. If the combined shock and fatigue factor for bending is 1.5 and combined shock and fatigue factor for torsion is 2, then the equivalent twisting moment for the shaft is 2050 N-m 2100 N-m 2136 N-m 2000 N-m 2050 N-m 2100 N-m 2136 N-m 2000 N-m ANSWER DOWNLOAD EXAMIANS APP

Machine Design The connecting rod bolts are tightened up with initial tension greater than the external load so that Bolts are weakest elements Joint may not open up The resultant load on the bolt would not be affected by the external cyclic load Bolts will not loosen during service Bolts are weakest elements Joint may not open up The resultant load on the bolt would not be affected by the external cyclic load Bolts will not loosen during service ANSWER DOWNLOAD EXAMIANS APP
Machine Design Two helical springs of the same material and of equal circular cross-section, length and number of turns, but having radii 80 mm and 40 mm, kept concentrically (smaller radius spring within the larger radius spring), are compressed between two parallel planes with a load W. The inner spring will carry a load equal to 8W/9 W/2 2W/3 W/9 8W/9 W/2 2W/3 W/9 ANSWER DOWNLOAD EXAMIANS APP
