Machine Design In replacing the V-belts, a complete set of new belts is used instead of replacing a single damaged belt because Only one belt cannot be fitted with other used belts The new belt will carry more than its share and result in short life Belts are available in sets New and old belts will cause vibrations Only one belt cannot be fitted with other used belts The new belt will carry more than its share and result in short life Belts are available in sets New and old belts will cause vibrations ANSWER DOWNLOAD EXAMIANS APP
Machine Design The elasticity is the property of a material which enables it to Regains its original shape after deformation when the external forces are removed Draw into wires by the application of a tensile force Resists fracture due to high impact loads Retain deformation produced under load permanently Regains its original shape after deformation when the external forces are removed Draw into wires by the application of a tensile force Resists fracture due to high impact loads Retain deformation produced under load permanently 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 Bolts will not loosen during service The resultant load on the bolt would not be affected by the external cyclic load Bolts are weakest elements Joint may not open up Bolts will not loosen during service The resultant load on the bolt would not be affected by the external cyclic load ANSWER DOWNLOAD EXAMIANS APP
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 2.5 3 3.5 2.8 2.5 3 3.5 2.8 ANSWER DOWNLOAD EXAMIANS APP
