Question 1) The figure shows a person wearing weight boots and doing lower leg flexion/extension exercise in sitting position to strengthen the quadriceps muscles and a simple mechanical model of his leg. W 1 is the weight of the lower leg, Wo is the weight of the boot, FM is the magnitude of the pulling force exerted on the tibia by the quadriceps muscles through the patellar tendon, F, is the magnitude of the reaction force acting on the tibiofemoral joint. Point O is the center of the tibiofemoral joint, Point A is the point where the patellar tendon attaches to the tibia, Point B is the center of gravity of the lower leg, C point of gravity is the center of gravity of the boat. The distances between point O and points A, B and C were measured as a = 10 cm, b=22 cm and c=43 cm, respectively. The angle between the long axis of the tibia and the horizontal is B=38°, the angle between the action line of the quadriceps muscle strength and the long axis of the tibia is a=18°. Points O,…

4. You have been tasked with retrieving a crate from a 4-m long beam that is suspended by two cables, as shown. While standing 1.5 m from the left edge of the beam, you silently hope that the cables are strong enough to hold the weight of the beam, the box, and you! The masses of the beam and you are 10 kg and 70 kg, respectively. The cables are rated for a tension of 1000 N. Do the cables hold? In other words, what is the tension in each cable? Hint: you can assume the box is sitting on the very end of the beam. 30° 20° 4.0 m
