A4.3 In the figure on the right, wheel 2 is 3.1" in radius and wheel 3 is 10.5" in radius. Wheel 2 rotates at 115 rev/min and drives wheel 3 without slipping. Find the velocity difference between the two points on wheel 3: B (9.5" from O3) and A (10.5" from O3). Draw the velocity polygon (ie. the loop of vectors in velocity space). Note: Elements in the drawing are not shown to correct scale. 3 10.5" -9.5" B A W2115 rev/min 3.1" A4.3 In the figure on the right, wheel 2 is 3.1" in radius and wheel 3 is 10.5" in radius.
