Problem 11.A skeletal diagram of the lower leg is shown in thelower figure. Here it can be noted that this portion of the legis lifted by the quadriceps muscle attached to the hip at Aand to the patella bone at B. This bone slides freely overcartilage at the knee joint. The quadriceps is furtherextended and attached to the tibia at C. Using themechanical system shown in the upper figure to model thelower leg, determine the tension in the quadriceps at C andthe magnitude of the resultant force at the femur (pin), D,in order to hold the lower leg in the position shown. Thelower leg has a mass of 3.2 kg and a mass center at G1; thefoot has a mass of 1.6 kg and a mass center at G2.75 mm25 mmВ350 mm300 mmА756В.D, = 840.20 NANS:B,

The figure on the left, below, shows a non-uniform bent rod with a mass of 5 kg. Your job is to determine the location of the center of gravity of this rod. You design an experiment: you connect a pin and cable to the rod such that it safely stays in static equilibrium under a force P that you apply. Then, you apply forces between 0-100 N, and measure the tension force on the cable using a cable tension meter. The results of your experiment are shown in the figure, on the right. Using this experiment, calculate (approximately) the horizontal distance (x in the figure) between point A and the center of gravity G of the bent rod.

Problem. Consider the following problem. Find the displacement of node 4. Assume F2=200 N, F3=300 N, F4=400 N and Kı= 100, K2= 200, and K3= 300 N/mm. F. 3 2 3 4 Note: The stiffness matrix of individual springs should be first written, then the equilibrium equations at each node should be written, expanded in terms of nodal displacement, and used to perform the assembly of the global stiffness matrix of the problem. Then, the appropriate boundary conditions should be applied and the nodal displacement vector should be found. Every step should be shown; missing any step would result in point deduction even if the final answer is correct.
