Calculating with Torgue: Dynamics of Rotation Hint: Optimal break-up of the four-step process here might be one instance for Q1 and 02 together, and a second for 0,3 alone. This is merely a suggestion, and you could apply the four-step process once to all three questions together, but my advice for a more 'logical' breakup is to apply twice: once to the 'grouping' of Q1 and 02. and a second time to 0,3. The grader will not be looking for any specic break-up, so it is up to you. Cu: In the overhead View of the figure shown below, five forces of the same magnitude F act on a strange merry-go-round; it is a square that can rotate about point P, at mid-length along one of the edges. Rank the magnitudes of the torques created {individually} by each of the five forces [1 5] about point P, from greatest to least: Explain your ranking. Hint: because you are considering magnitude only, all your torque terms will either be positive or zero in the determination ofyour ranking. Q2: The gure below shows three different scenarios in which the same horizontal rod is supported by a hinge on a wall at one end and a chord at its other end. Rank the three scenarios according to the magnitudes ofthe three chord forces [[1] 121, {311, needed to support the rod in each, from greatest to least. Explain your ranking. Hint: In all three scenarios, the same magnitude chord torque is required to support the rod. E7 {2} {Ill 03: Part A: On a playground, there is merry-go-round. In order to get it moving you apply a force of 41 N. The merry-go-round measures 7.1 m from the axis of rotation to the edge where you apply your force. Assuming you apply your force perpendicular to a line drawn from the axis of rotation, what is the magnitude of torque imparted to the merry-go-round? Part B: Now, assume that there is a massless handle attached to the merry-go-round closer in on its center than its edge, that you can grab onto to apply a \"new\" force. You want this 'new' force to be applied perpendicular to the line drawn from the {same} axis of rotation as before, and you want this 'new' force to impart the same magnitude torque about the center of the merry-go-round as before. Will the magnitude of this 'new' force be greater than less than or egual to that of the original force [in Part A]?Justi your answer. - Getting Started: State the important information and summarize the problem. If possible. include a diagram. Note any assumptions you're making. - Devise Plan: Devise a plan of attack before diving into the solution. Break down the problem into smaller, manageable segments. Identify which physical relationships you can apply. - Execute Plan: Carry out your plan, explaining each step. The argument should be easy to follow. Articulate your thought process at each step {including roadblocks]. Any variables should be clearly defined, and your diagrams should be labeled. - Evaluate Solution: Check each solution for reasonableness. There are many ways to justify your reasoning: check the symmetry of the solution, evaluate limiting or special cases, relate the solution to situations with known solutions, check units, use dimensional analysis. andior check the
