Unformatted text preview: axis is translating like the center of the crank and the center of the wheel. We will talk more about rolling wheels later in the quarter. Now find the angular velocity of the rear spocket = angular velocity of rear wheel Similarly, find the velocity of the point on the wheel that touches the ground which equals the speed of the bike v chain =r crank ω crank Vchain=0.12*1rev/s*2π/rev Vchain=0.75 m/s ϖ wheel =v chain /r sprocket ϖ wheel =0.75/0.045 ϖ wheel = 16.76 rad/s v bike = r wheel ϖ wheel v bike = 5.53 m/s...
