Problem A person is doing leg exercises where a 100N weight linked via a pulley is attached to their heel. Based on a simplified system in which the quadricep muscles are the only active muscle group and can be modeled as a single muscle tension, what is the muscle tension and joint reaction force at the knee necessary to maintain this position. You can assume the quadriceps is attached to the tibia 5 cm below the knee, making a 15° angle with the horizontal. The weight of the leg is 120 N and the center of gravity is 0.35 m from the knee joint, and the length of the leg is 0.8 m. Make sure to draw a FBD of the lower leg. 100N

Muscle 2 E Muscle 1 0₁29 1 dM1 dM₂ dw Ow W dDB Ow Hand Dumbbell The figure provides a free body diagram of several forces acting about the elbow joint (E) for an isometric elbow flexion exercise. In this case, the subject is holding a 279 N dumbbell (located dpB = 48 cm from the elbow) in a stationary position. W is the combined weight of the forearm and hand (28 N) and acts through the CG of this system (located dw = 19 cm from the elbow). The forearm is elevated from the horizontal, resulting in a 0w = 74 deg angle between the forearm and line of action of each weight. The force produced by Muscle1 is 964 N (with an angle of pull of 0M1 = 53 deg and an insertion length of dm1 = 5 cm from the elbow). Muscle2 has an angle of pull of 0m2 = 24 deg and an insertion length of dm2 = 8 cm from the elbow. What is the force magnitude of Muscle2 required to keep the elbow in a stationary position? You are allowed a 5% margin of error for rounding.
One of your employees is complaining of knee pain on the R. While assessing his workstation, you noted that from a sitting position (starting position: 90 deg flexion), the employee needs to exert a lot of effort to extend his right knee to 45 deg from the starting point. The length of the limb (from the tibial tuberosity to the heel area) is measured to be 38 cm. What now is the linear distance traveled by the limb from the initial position to 45 degrees of knee extension?
5 non-concurrent forces are acting on two rings connected by a line that resulted in equilibrium. can you help me solve this equilibrium of forces question using the polygon method? the pieces of string are tied to a massless rings. the forces acting on the ring are in gram-force. thank you.
3. From the results you obtained in this laboratory, compute the net muscle force in the biceps brachii necessary to maintain the forearm at a right angle relative to the upper arm using the centre of gravity values for the forearm segment obtained using Clauser, Dempster and Zatsiorsky's tables and given that the muscle inserts 5 cm from the elbow joint (think back to Lab 5 - Moments of Force). Assume that the muscle acts at 90° to the forearm and that there is not an additional weight in the hand. cg

During a bicep curl on a bicep curl machine, I'm curling a weight stack of 100 pounds (single arm...I'm jacked like that). At this very moment, the weight stack has a moment arm of 0.12m, my elbow has an angle of 63deg, my muscle force vector has an angle of 23deg, and it attaches 3cm below my elbow joint on my radius. How much force must my bicep create right at this moment to hold the weight stack in place?
Pregnancy shift of com. Figure gives a simplified view Forefoot x=0 f(mg/2) com Heel -x h(mg/2) of the weight supported on each foot of someone with weight mg standing upright with half the weight supported by each foot. An x axis lies along the foot, with x = 0 at the forefoot and x = 25 cm at the heel. On each forefoot the downward force is f(mg/2), where f is the fraction of the weight on a foot that is supported by the forefoot. Similarly, on each heel the down- ward force is h(mg/2). The foot (and the person) is in equilib- rium around the center of mass. During pregnancy, the center of mass shifts toward the heels by 41 mm. What percent of the weight shifts toward the heels? (The center of mass shifts back to its initial position after pregnancy.)

BY 1.20 cm 7. QIC A simple pendulum consists of a small object of mass 3.0 kg hanging at the end of a 2.0-m-long light string that is connected to a pivot point. (a) Calculate the magnitude of the torque (due to the force of gravity) about this pivot point when the string makes a 5.0° angle with the vertical. (b) Does the torque increase or decrease as the Figure P8.6 angle increases? Explain.
