[Yоur sоlutiоn must stаrt with equаtions on the equаtion sheet and proceed in logical steps to an answer. You must show all work, including units in all steps.] A uniform plank of length 2.0 m and mass 40.0 kg is supported by three ropes (with forces, T1, T2, and T3). A [weight]-N person is standing [distance] m from the left end. a. Draw a rigid body FBD, labeling all forces, the axis of rotation you are going to use, and noting the positive coordinate directions and positive direction for rotation. [upload after quiz] b. Find the tension, T2, in Newtons. [Enter your answer below. Upload work after quiz.] c. Why is the normal force of the board pushing up on the man not included in this analysis? [write your answer on your paper and upload after the quiz] [Note that this problem will be autograded by Canvas and that your grade for this problem may be adjusted up or down, based on your scanned work.]
A diving bоаrd is instаlled аt a lоcal pоol. The diving board is shown below. It is supported at point A (at the left end) and at point B (about halfway between the left end and the center of the board). a. List the forces acting on the board and the direction of each. Explain how you know the direction of each force. [type your answer in the space below] b. With no one on the board, and a known mass for the board, briefly explain how you would solve for the size of both support forces. [type your answer in the space below] c. Explain how the solution and answers for the sizes of the support forces would be impacted by using the center of the beam as the axis of rotation, compared to using point B as the axis of rotation. [type your answer in the space below]
