machine, the testis carried to the breakdown point. Starting Torque Test. The stationary or starting torque de-veloped by a motor determines the amount of load under whichit will start. To perform this test a brake is clamped to the pulleyas shown in Fig. 359. A is the center of the pulley; B is… … Fig. 359.
