What are the two different forces acts in opposite direction on the rotor of single phase induction motor?
An induction motor has an AC power source applied to the stator and an AC source applied to the rotor, through slip rings. The rotor spins a sub synchronous speed, which creates the phase shift between rotor AC and stator AC. This phase shift (known as slip) is what creates the torque.

What is Cross field revolving theory?
Cross field revolving theory is the theory which discuss the cause of single phase induction motor not to be self starting. According to it, two different forces of same magnetude acts on the rotor in just opposite direction.Which makes the rotor standstill.
Define shear force?
Shear forces are ranged forces pushing one part of a body in a direction and another part in opposite directions. An example is when you pushed a deck of cards one way at the top and another at the bottom causing the cards to slide.
Where is flemings left hand and right hand rules are used in operation of induction motor?
For conventional flow (plus to minus) FLH rule is for motor action, and FRH rule is for generator action. So you can use FRH rule to determine the direction in which voltages are induced into the rotor by the rotating magnetic field, then use FLH rule to determine the direction in which the resulting forces, due to the rotor-bar currents, will act to rotate the rotor.
Why a three phase induction motor is self stating?
when you excite the 3-phase coils with an alternating supply,It produces a rotating magnetic field which interacts with the windings/conductor on the rotor & produces a current. According to Lenz's law the current induced is opposite in nature to the cause producing it & hence the magnetic field produced by this current will be opposite in nature to the rotating magnetic field in the stator.Hence due to interaction of these two forces a torque will be acting on the rotor which will make the rotor to rotate. Hence it is self-starting .
What is non concurrent force system?
In a concurrent force system, all forces pass through a common point. In the previous case involving the application of two forces to a body, it was necessary for them to be colinear, opposite in direction, and equal in magnitude for the body to be in equilibrium. If three forces are applied to a body, as shown in the figure, they must pass through a common point (O), or else the condition, SMo= 0, will not be satisfied and the body will rotate because of unbalanced moment. Moreover, the magnitudes of the forces must be such that the force equilibrium equations, SFx= 0, SFy= 0, are satisfied.
What is called two forces that are equal in size but opposite in direction are?
Two forces that are equal in size but opposite in direction are called balanced forces.
Forces that are equal in size but opposite in direction are called unbalanced forces?
Actually, forces that are equal in size but opposite in direction are called balanced forces. Unbalanced forces are forces that are not equal in size and/or opposite in direction, resulting in a change in an object's motion.
Why don't two forces balance each other?
Two forces may not balance each other if they are acting in different directions or have different magnitudes. When forces are not equal and opposite, they result in acceleration or movement of the object in the direction of the greater force.
What is the Difference between like and unlike parallel forces?
Forces which are parallel and acting in same direction are called like parallel forces. Forces which are parallel and acting in opposite direction are called unlike parallel forces.

Is acceleration caused by two forces which are opposite to each other?
No, acceleration is caused by an imbalance of forces acting on an object. If the two forces are equal in magnitude and opposite in direction, they will cancel out and there will be no acceleration. Acceleration occurs when there is a net force acting on an object.
