Theory of Machine The velocity of a body moving with simple harmonic motion is __________ at the mean position. None of these Zero Maximum Minimum None of these Zero Maximum Minimum 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 forces are not dangerous at higher speeds Unbalanced couples are caused only at higher speeds Effects of unbalances are proportional to the square of the speed Effects of unbalances are directly proportional to the speed Unbalanced forces are not dangerous at higher speeds Unbalanced couples are caused only 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
Theory of Machine If the rotating mass of a rim type flywheel is distributed on another rim type flywheel whose mean radius is half the mean radius of the former, then energy stored in the latter at the same speed will be Same as the first one One and a half times the first one One fourth of the first one Four times the first one Same as the first one One and a half times the first one One fourth of the first one Four times the first one ANSWER DOWNLOAD EXAMIANS APP
