A person exercises the quadriceps as shown. The diagram on the right shows a model of the leg, where the person's lower leg of length L = 0.55 m is held at an angle 0₁ = 45° with respect to the horizontal. The quadriceps muscle exerts a force FM via the tendon that attaches to the tibia at a distance d = 0.10 m from the knee, in order to lift a weight of mass m₁ = 20 kg that is attached to the foot. The tendon makes an angle of 02 = 20° with respect to the tibia. What is the force required to hold the weight at the position shown in the diagram? Assume the person's lower leg weighs 145 N and its centre of mass is located at a distance L/2 from the knee. Round your answer to the nearest Newton. 02 01 A person exercises the quadriceps as shown.
