Example 11.3. A shaft which rotates at a constant speed of
160 r.p.m. is connected by belting to a parallel shaft 720 mm apart,
which has to run at 60,80 and 100 r.p.m. The smallest pulley on the
driving shaft is 40 mm in radius. Determine the remaining radii of
the two stepped pulleys for 1. a crossed belt, and 2. an open belt.
Neglect belt thickness and slip.
