The displacement of the D-slide valve is __________ the steam lap by a distance known as lead of the valve.
-
In the two rotor system as shown in the below figure (I1 < I2), a node of vibration is situated
-
For static balancing of a shaft, the net dynamic force acting on the shaft is equal to zero.
-
A spring controlled governor is said to be unstable, if the relation between the controlling force (Fc) and radius of rotation (r) is Fc = ar.
-
The rotor of a ship rotates in clockwise direction when viewed from stern and the ship takes a left turn. The effect of gyroscopic couple acting on it will be
-
Most of the engines, generally, do not require balancing of secondary forces and couples.
