You are able to hold your arm in an outstretched position
because of the deltoid muscle. The force diagram for this is shown
below. Assume that the weight of the humerus is 8 lb (with a center
of gravity as shown), and that the deltoid muscle makes an angle of
α = 18 degrees to the humerus.
What is the magnitude of the tension in the deltoid muscle? What
is the magnitude of the force F at the joint?
Deltoid...

Muscle force Axis w The mass and length of the forearm in the diagram below are 2.2 lbs. and 0.1 m, respectively. Calculate the torque generated by the weight of the forearm, assuming the weight of the forearm is located halfway along the forearm (1 kg = 2.2 lbs.).

An athlete is measuring the force by their flexor muscle by pulling a rope horizontally at a constant force. While pulling the rope the muscle applies a force on the forearm an angle of 71° as shown in the diagram. While keeping your forearm completely vertical, the tension in the rope is at 185N. The athlete's muscle is attached to the forearm 5 cm from the elbow joint and that the weight of your forearm is 22 N with a...

Consider the case of the bicepts muscle acting on a forearm
holding a 43 N weight. The forearm is 30° below the horizontal and
the bicepts muscle inserts at an angle of 45° with the forearm. The
muscle insertion is at 5 cm from the elbow joint. The forearm has a
weight of 21 N and has its center of gravity 15 cm from the elbow.
The 43 N weight is held in the hand 30 cm from the joint...

Consider the case of the bicepts muscle acting on a forearm holding a 35 N weight. The forearm is 30 below the horizontal and the bicepts muscle inserts at an angle of 45 with the forearm. The muscle insertion is at 5 cm from the elbow joint. The forearm has a weight of 18 N and has its center of gravity 15 cm from the elbow. The 35 N weight is held in the hand 30 cm from the joint...

Deltoid muscle Fig. 1a Problem #2.1 You are able to hold your arm in an outstretched position because of the deltoid muscle. The force diagram for this is shown in Fig. 1b. Use the equilibrium conditions to determine the tension T in the deltoid muscle needed to achieve this equilibrium, and the vertical and horizontal components of the force exerted by the scapula (shoulder blade)on the humerus. Assume the weight of the humerus is 36.0 N and the deltoid muscle...
