Question

1. Two parallel shafts, 11 in. apart and rotating at 75 rpm and 200 rpm, are connected by cylinders in pure

rolling contact. Determine the diameters of the cylinders: (1) when they turn in opposite directions; and (2)

when they turn in the same direction.

2. Two parallel shafts connected by rolling cylinders turn in the same direction 150 rpm and 100 rpm

respectively. The smaller cylinder is 16 in. in diameter. How far apart are the axes of the shafts?

3. Two parallel shafts, 24 inches apart and having a speed ratio of 3, are connected by cylinders in pure rolling

contact. Determine the diameters of the cylinders: (1) when they turn in opposite directions; and (2) when

they turn in the same direction
