Torque Diagram Mcqs. 8 opening a door if r is perpendicular to f then torque τ r f if r is not perpendicular to f then torque τ. In diagram 2 the two parallel forces have each moved l4 to the left.
Hence the torque is zero because the line of action of the tension passes through the centre so lever arm of tension is zero so the torque acting is also zero. T po pull out breakdown or maximum torque obtainable over the entire speed range. The rotor of the slip ring induction motor is connected to an ac source and stator is short circuited.
If the rotor circuit resistance of a 3 phase induction motor is increased then.
Torque diagram showing forces and lever arms. Shows the phasor diagram of the capacitor start induction motor. It is plotted on cartesian coordinates in which the turning moment is taken as the ordinate and crank angle as abscissa. Phasor diagram.
