Theory of Machine In an open pair, the two elements of a pair Are not held together mechanically Have a line or point contact when in motion Have a surface contact when in motion Are kept in contact by the action of external forces, when in motion Are not held together mechanically Have a line or point contact when in motion Have a surface contact when in motion Are kept in contact by the action of external forces, when in motion 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 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 Unbalanced couples are caused only at higher speeds Unbalanced forces are not dangerous at higher speeds ANSWER DOWNLOAD EXAMIANS APP
