Abubakar Tafawa Balewa University BME 465 Uniform Horizontal Beam Exercices answer all the questions please if you need anything just text me thanks attachment_1 BME 465 Homework 5 For all problems include your free body diagram, units and direction when applicable. 1. Assuming a static system, and a uniform horizontal beam that is attached at point A and has a frictionless support at point D. An 80 kg person is standing at point B. If the distance AB is 6m and AD is 2m and the board is 1500 N. What is the reaction force at points A and D (include units and direction). (10 points) 2. Consider the following static system. The leg is held in position by 2 weights that are connected by cables. The combined weight of the leg and cast is 300 N. using L as the horizontal distance between AB. Point C is the center of gravity of the leg and cast and is 2/3L measured from point A (as in closer to point B). The angle of cable 2 (beta) is 45o. Determine the tension in cable 1 and cable 2, the weight of weight 1 and 2 and the angle that cable 1 is making with the horizontal (alpha). (10 points) 3. Consider the following static system with a horizontal beam hinged to the ground at point A. The overall length of the beam is 4.5 m and weighs 650N. Point C is the center of gravity of the beam. An 850 N force (P) is applied at point B with an angle of 45o. A box weighing 125 N is placed at point E and the distance between the boxs center of gravity and point B is 0.3 m (l1). Finally a frictionless roller is placed at point D to prevent counterclockwise rotation and the distance from AD is 3m (l2). BME 465 Homework 5 Calculate the reactions at point A and D, include the X and Y components as well as the overall magnitude and angle of application. (10 points) 4. Assume a static analysis of the following problem. A person is wearing a weighted boot. In this simplified model of the lower leg, W1 is the weight of the lower leg, Wo is the weight of the boot, FM is the tensile force of the quadriceps via the patellar tendon, and FJ is the tibiofemoral joint reaction force applied on the tibial plateau. Point O I the joint center, the patellar tendon is attached at point A, the center of gravity for the lower leg is at B and the center of gravity of the boot is at point C. For distance OA use a, OB b, and OC c. The long axis of the tibia makes angle ? with the horizontal axis and the line of action of the quadriceps muscle is ? with respect to the long axis of the tibia. Assuming O, A, B, and C are on a straight line determine FM and FJ in terms of a, b, c, W1, Wo, ?, and ?. Include X and Y components as well as the overall magnitude and angle of application.
