The torque transmitted to an induction motor is a function of the slip between the rotation of the stator field and the rotor speed s, where slip is defined as

where n = revolutions per second of rotating stator speed and n_R = rotor speed. Kirchhoff’s laws can be used to show that the torque (expressed in dimensionless form) and slip are related by

Figure P7.34 shows this function. Use a numerical method to determine the slip at which the maximum torque occurs.
