Two weights WB and We are supported by three cables (AB, BC, and CD), as shown in the figure below. The vertical distances between points A & B, B & C, and C & D are given by hAB = 10.5 m, hBc = 3.5 m, and hcp = 7.5 m respectively.

The arm in the figure below weighs 41.6 N. The force of gravity acting on the arm acts through point A. Determine the magnitudes of the tension force Ft in the deltoid muscle and the force Fs exerted by the shoulder on the humerus (upper-arm bone) to hold the arm in the position shown. F 0.080 m -0.290 m TE br

It was known that there are five members concurrent at joint A isolated in the figure below. Out of those five member forces, the magnitude and direction of three member forces are known and shown in the figure below. Calculate the remaining unknown member forces F1 and F2, so that equilibrium of forces is satisfied at joint A.

Four sets of flexible cables, spaced at 120° intervals, are used to stabilize a 400-ft communications tower. The tower and one cable from each set is shown in Fig. The weight of each tower is 40 lb/ft, and the communica- tions equipment at the top weighs 2000 lb. Determine the axial forces transmitted by transverse cross sections at points A, B, C, and D of the tower. 50 ft 30 1500 lb 100 ft B 40° 1250 lb 100 ft 50° 1000 lb 100 ft 50 ft 60 750 Ib
