Theory of Machine The factional torque for square thread at the mean radius r while raising load W is given by T = W.r tanα T = W.r tanφ T = W.r tan(φ - α) T = W.r tan(φ + α) T = W.r tanα T = W.r tanφ T = W.r tan(φ - α) T = W.r tan(φ + α) ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The component of the acceleration, perpendicular to the velocity of the particle, at the given instant is called Tangential component Coriolis component Radial component None of these Tangential component Coriolis component Radial component None of these ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the speed of the engine fluctuates continuously above and below the mean speed, the governor is said to be Hunt Isochronous Unstable Stable Hunt Isochronous Unstable Stable 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 directly proportional to the speed Effects of unbalances are proportional to the square of the speed Unbalanced forces are not dangerous at higher speeds Unbalanced couples are caused only at higher speeds Effects of unbalances are directly proportional to the speed Effects of unbalances are proportional to the square of the speed Unbalanced forces are not dangerous at higher speeds Unbalanced couples are caused only at higher speeds ANSWER DOWNLOAD EXAMIANS APP
