Question 4 a). A gear reduction system consists of three gears A, B, and C is shown in Figure 4a. Knowing that gear A rotates clockwise with a constant angular velocity w=600 rpm, determine i. the angular velocities of gears B and C, ii. the accelerations of the points on gears B and C which are in contact. 2 in. 2 in. 4 in. 6 in. Figure 4a [10 marks] b). A barrel and its contents have a combined mass of 90 kg. A cylinder C is connected to the barrel at a height h=550 mm as shown in Figure 4b. Knowing p=0.40 and = 0.35, determine the maximum mass of C so the barrel will not tip. 500 mm [15 marks] 900 mm 450 inin G Figure 4b 4/4 End of Paper
