If the crank shaft G is turning with angular speed ωG , determine the angular speed of the drive shaft H. Each of the gears rotates about a fixed axis. Note that gears A and B, C and D, and E and F are in mesh. The radii of each of these gears are listed. Given: ωG = 60 rad s rA = 90 mm rB = 30 mm rC = 30 mm rD = 50 mm rE = 70 mm rF = 60 mm Solution: ωB = ωD = ωH = rA rB ωG ωB = 180.00 rad ωB ωD = 108.00 rad ωD ωH = 126.00 rad rC rD rE rF s s s 413 ...
