1.1 With the aid of diagram(s) and equation(s), explain two (2) possible approaches that can be applied to solve kinetics of rigid bodies' problems. 1 1.2 The gear rotates clockwise about fixed axis at the constant speed of 180 rpm. Given AB = DC = 200 mm, BC = 750 mm, 0 = 30°, and the mass of rod BC, mBc = 7.5 kg. Determine at the instant shown the vertical forces exerted by the pins at B and C on rod BC.
