Balancing of Rotors:
Balancing of Rotors is essential to avoid the vibration of the machine. Rotors are balanced either statically or dynamically. Static balancing is done by adding weight to the lighter side of the rotor until it becomes balanced. Dynamic balancing is done by adding or removing weight from the rotor in such a way that the center of gravity coincides with the axis of rotation.
Given Condition:
Two rotors are mounted on a shaft. If the unbalanced force due to one rotor is equal in magnitude to the unbalanced force due to the other rotor, but positioned exactly 1800 apart, then the system will be balanced.
Explanation:
When two unbalanced forces are equal in magnitude and opposite in direction, they are said to be in equilibrium. If these forces act on a rigid body such that their lines of action are different, then the body will not be in equilibrium. However, in this case, the two rotors are mounted on a shaft and positioned exactly 1800 apart. Since the unbalanced forces due to the two rotors are equal in magnitude and opposite in direction, they will cancel out each other's effect and the system will be balanced statically.
However, it is important to note that the system may not be balanced dynamically. Dynamic balancing requires that the center of gravity of the rotor coincides with the axis of rotation. If the two rotors are not balanced dynamically, then the system may vibrate.
Conclusion:
Thus, in this given condition, the system will be balanced statically but may not be balanced dynamically. It is necessary to balance the rotors dynamically to avoid vibration and to ensure smooth operation of the machine.
