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.
Part A
PC
A cable is attached to a 1.10 kg block A, is looped over a fixed peg at C, and is attached to plate B. The coefficient of
static friction between the plate and the block is μA = 0.200,
the coefficient of static friction between the plate and the
inclined plane is μB = 0.390, and the coefficient of static
friction between the cable and the peg is c = 0.230. If the
plane's angle is 30.0 degrees, what is the maximum mass
that plate B can have such that it does not slide down the
plane?
Express your answer numerically in kilograms to three
significant figures.
