Question

The figure shows the finishing position of a body builder's arm who is performing a standing lateral raise with
a 5.00-kg dumbbell. This is an excellent exercise that isolates the lateral deltoid muscle. The weight of the arm
itself is 42.5 N, and it acts at point A in the figure. Given the information shown, and the fact that 0 = 9.74°,
(a) find the magnitude of the tension force in the deltoid (F₁) and (b) the normal force from the shoulder
joint (F
acting on the humerus bone that holds the arm in this equilibrium position.

A person is performing slow arm curls with 10-kgWeight as idicated in the left image of the figure below. The biceps group (consisting of the biceps and brachialis muscles) is the major factor in this exercise. Determine the magnitude F7 of the biceps group force and the magnitude 4 of the elbow joint reaction at point E for the forearm position. The free body diagram is shown in the right image of the figure. Take the dimensions shown to locate the effectivepoints of application of the biceps group; these points are 200 mm directly above E and 50 mm directly to the right of E. Include the eftect of the the 1.5-kg forearm mass with mass center at point G. Assuming that humerus is perfectly vertical and fixed; therefore, the elbow joint E is acting like pin connection. The forearm (E-B-G-C) is perfectly horizontal; therefore, the angle A-E-B is 90 deg.

The lumbar portion of the human spine supports the entire weight of the upper torso and the force load imposed on it. We consider here the disk (shaded red) between the lowest vertebra of the lumbar region (L5) and the uppermost vertebra of the sacrum re- gion. (a) For the case L = 0, determine the com- pressive force C and the shear force S supported by this disk in terms of the body weight W. The weight W. of the upper torso (above the disk in question) is 68% of the total body weight W and acts at Gj. The vertical force F which the rectus muscles of the back 25 mm L3 L4 L5 G2 4r exert on the upper torso acts as shown in the figure. (b) Repeat for the case when the person holds a weight of magnitude L assumptions. W/3 as shown. State any Sacrum %3D 300 mm 50 mm 3王

The figure on the left, below, shows a non-uniform bent rod with a mass of 5 kg. Your job is to determine the location of the center of gravity of this rod. You design an experiment: you connect a pin and cable to the rod such that it safely stays in static equilibrium under a force P that you apply. Then, you apply forces between 0-100 N, and measure the tension force on the cable using a cable tension meter. The results of your experiment are shown in the figure, on the right. Using this experiment, calculate (approximately) the horizontal distance (x in the figure) between point A and the center of gravity G of the bent rod.
