Pulley Problems » S A thought-provoking pulley problem Here's a pulley problem that makes you think more deeply about the pulley kinematics recipe presented in the previous video. It also make you think more deeply about whether a pulley problem is well posed or not. m1 m2 m1 7n2 -8 When I presented pulley system on the left to the class, many students thought it was ill-posed. The blocks and pulleys wouldn't pull against each other. The rope would go slack. Instead, they suggested that the slope of the ramp be reversed as depicted on the right So here's the main question. Which of the two pulley systems shown above is well-posed? In other words, for which of the two systems does the rope provide a tension force that keeps the pulleys engaged and active in the dynamics. Provide a rigorous justification. For the well-posed system, derive an expressiou for the rope tension in terms of mi, m2, 9, and
