A 72.0 kg weightlifter doing armraises holds a 7.50 kg weight.Her arm pivots around theelbow joint, starting 40.0° belowthe horizontal (Fig.).Biometric measurements haveshown that, together, the forearmsand the hands account for 6.00%of a person’s weight. Since theupper arm is held vertically, thebiceps muscle always acts verticallyand is attached to the bonesof the forearm 5.50 cm from theelbow joint. The center of mass of this person’s forearm–hand combinationis 16.0 cm from the elbow joint, along the bones of the forearm,and she holds the weight 38.0 cm from her elbow joint. (a) Draw a freebodydiagram of the forearm. (b) What force does the biceps muscleexert on the forearm? (c) Find the magnitude and direction of the forcethat the elbow joint exerts on the forearm. (d) As the weightlifter raisesher arm toward a horizontal position, will the force in the biceps muscleincrease, decrease, or stay the same? Why?
Given that the weight of the lower arm is Mg = 16.0 N , and that the force meter reads F = 87.0 N , what is the force FT exerted vertically upward by the triceps?
While doing a back squat, you're doing reps with 300 pounds on the barbell (total mass of the barbell and weights; you're strong...you got this!). At the bottom of your squat, your hip is flexed to a 45deg angle, your knee is flexed to a 90deg angle, and your ankle is dorsiflexed to 75deg. The force vector of the barbell is 15cm anterior from the hip joint, 20cm posterior from the knee joint and 12cm anterior from the ankle joint. How much torque is the barbell applying to the hip joint? 138.29Nm extension torque 160.53Nm extension torque 200.66Nm flexion torque News team....ASSEMBLE!!!!!! O 267.55 Nm flexion torque
Suppose the hand in (Figure 1) holds an 8.9 kg mass. The total mass of the arm is 3.3 kg. What force, FM, is required of the deltoid muscle, assuming the mass is 47 cm from the shoulder joint? Express your answer to two significant figures and include the appropriate units.
Everett is attempting to lift 112 N. The perpendicular distance from the weight to his elbow joint is 21 cm. Theforce created by the elbow flexor muscles is 1485 N. The perpendicular distance from this force to the elbow jointis 1.8 cm. Is Everett able to lift the weight with this amount of force in his flexor muscles?
the bones of the forearm (radius and ulna) are hinged to the humerus at the elbow. The biceps muscle connects to the bones of the forearm about 2.152.15 cm beyond the joint. Assume the forearm has a mass of 2.152.15 kg and a length of 0.4050.405 m. When the humerus and the biceps are nearly vertical and the forearm is horizontal, if a person wishes to hold an object of mass 4.954.95 kg so that her forearm remains motionless, what is the force ?F exerted by the biceps muscle?

During most of the stance phase of the gait, the knee flexion is less than 20º. What force must the quadriceps muscle apply to maintain this flexion while standing on one leg? The patient's weight is 836N, assuming that the distance from the center of the joint to the line of gravity is 5 cm and the distance perpendicular to the center of the joint towards which the muscle acts is 5 cm, and the muscle acts ( pull) at 60º to the horizontal.
Find the force exerted by the biceps muscle in holding a 1.00-L milk carton (weight 9.90 N) with the forearm parallel to the floor. Assume that the hand is 35.0 cm from the elbow and that the upper arm is 30.0 cm long. The elbow is bent at a right angle, and one tendon of the biceps is attached to the forearm at a position 5.00 cm from the elbow, while the other tendon is attached at 30.0 cm from the elbow. The weight of the forearm and the empty hand is 16.9 N, and the center of gravity of the forearm with hand is at a distance of 16.5 cm from the elbow.
