Torque Review (5 Problem Worksheet)
1. 110 N-m
2. 882 N for the cable farther from the painter, 1323 N for the cable closest to the worker
3. 1.14 m
4. .6 m from the fulcrum, located at .95 cm on the meter stick
5. Work is a scalar, torque is a vector
For work, force is parallel to x. For torque, force is perpendicular to x
Units: Work is in Joules (energy), torque is in N-m
