Chapter 8 Problem Solutions Giancoli
ANSWER: The linear or tangential velocity V=wR where R=1.2 m is the distance to the axis of rotation. The period of revolution is T=4.0 sec/cycle so the frequency f=1/4 cycles/sec= 0.25 Hertz an the angular frequency in radians per second is w=2pf=1.57 Rad/s. The linear speed V=wR=1.57 Rad/s ä 1.2 m =1.9 m/s.
Tutorial Sheet 7
11. A 220-V, 3-phase, 4-pole, 60-Hz squirrel cage induction motor develops a maximum internal torque of 250 percent of full load torque at a slip of 16 percent when operated at rated voltage and frequency. If the effect of stator resistance is neglected, determine the maximum internal torque that this motor would develop if it
