“DON’T STOP UNTIL YOU’RE PROUD
Question
A homogeneous (uniform, made of same material throughout) steel cylinder weighing 500 lb is
supported by a flexible cable and a smooth inclined plane as shown. (Figure b shows a FBD of the
cylinder; notice that all the force lines of action pass through the center of the cylinder, so this can be
thought of as an FBD of a particle at the center.) Determine the tension T (i.e., the magnitude of the
tensile force in the cable) and the normal force N exerted by the inclined plane on the cylinder.
Answer
“IT’S GOING TO BE HARD, BUT HARD DOES NOT MEAN IMPOSSIBLE”
