The blade of a portable saw and the rotor of its motor have a total mass of 1.75 kg and a combined radius of gyration of 30 mm. Knowing that the blade rotates as shown at the rate 2500 ω1 = rpm, determine the magnitude and direction of the couple M that a worker must exert on the handle of the saw to rotate it with a constant angular velocity ω2 = ?? (2.4 rad/s)j.
