Learning Goal:
To be able to analyze the equilibrium of systems
subjected to frictional forces at belts and surfaces.
When engineers design belt drives and band brakes,
they engineer them to withstand the frictional forces that
develop between the belts or bands and their contacting
surfaces. These frictional forces lead to tensions on each
side of the contacting surfaces that are unequal; the
segment aligning with the motion of the belt or band has
a greater tension
