Theory of Machine In multi V-belt transmission, if one of the belt is broken, we have to change the All the belts Broken belt and its adjacent belts There is no need of changing any one as remaining belts can take care of transmission of load Broken belt All the belts Broken belt and its adjacent belts There is no need of changing any one as remaining belts can take care of transmission of load Broken belt ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the Unbalanced couples are caused only at higher speeds Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed Effects of unbalances are directly proportional to the speed Unbalanced couples are caused only at higher speeds Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed Effects of unbalances are directly proportional to the speed ANSWER DOWNLOAD EXAMIANS APP
