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 Belts are available in sets New and old belts will cause vibrations The new belt will carry more than its share and result in short life Only one belt cannot be fitted with other used belts Belts are available in sets New and old belts will cause vibrations The new belt will carry more than its share and result in short life ANSWER DOWNLOAD EXAMIANS APP
Machine Design A plate with an elliptical hole in the centre, with semi-major axis (a) perpendicular to the direction of loading and semi-minor axis (b) along the direction of loading, is subjected to a pull P. The maximum stress induced at the edge of the hole is equal to (where σ = Stress for a plate with no hole i.e. nominal stress) σ [1 + (b/3a)] σ [1 + (3a/b)] σ [1 + (b/2a)] σ [1 + (2a/b)] σ [1 + (b/3a)] σ [1 + (3a/b)] σ [1 + (b/2a)] σ [1 + (2a/b)] ANSWER DOWNLOAD EXAMIANS APP
