Solution to Pairs Exercise #1

Solution to Pairs Exercise #1. T = Fr = (90 N)(0.08 m) = 7.2 N m q = (2 rev)(2 p rad/rev) = 4 p rad W = T q = (7.2 N m)(4 p rad) = 90.7 J. Solution to Pairs Exercise #2. w = (4000 rev/min)(2 p rad/rev)(1 min/60s) w = 419 rad/s P = (250 ft-lb)(419 rad/s)(1 hp/550 ft-lb/s)
