Q2 In Figure Q2, C and D represent brakes that can be used to stop the rotation of either arm E or gear 4, one at a time. Determine the speed and direction of shaft B when shaft A rotating at 1000 rpm CW, while (a) brake C holds arm E fixed. (b) brake D holds gear 4 fixed. N2 = 90; N3 = 32; N4 = 154; N5 = 94; N6 = 28

A single-strand roller chain drive connects a 50-hp engine to a lawn waste chipper/shredder, as shown below. As the engine operates at 1000 rpm, the shredding teeth should rotate at 250 rpm. The driven sprocket has 60 teeth. Determine the chain speed.
