Each of the free body diagrams below represent a disk that either is. or is not. in static equilibrium. In each of the cases below. indicate the newr force or forces that need to be added to the given free body diagram in order to bring the diskinto static equilibrium. If no additional forces are needed, state thisI and justify your answers in all cases: Hint: If the free body diagram does not represent a disk already in static equilibrium, then your answer will be a new free body diagram. with the original forces included, as well as the new force or forces that need to be added in order to 'bring the diskr to static equilibrium. These 'new forces' must be correctly indicated in direction, magnitude, and point of application relative to the letters A and B indicated in the original. Hint: Indicate all 'new force' magnitudes in terms of 'blue F' Hint: If no forces need to be added, then the free body diagram, as given, already represents a ball in static equilibrium. In this case, say so {no need to redraw], and justify. Hint: Sum all torques about the center of the disk taken as piyot {in purple} Case 1: , I r .I. C({fy-lllj'fr 17+". CiJ'E-V'\" - 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: lCheck 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, andfor check the
