Question
96 Fundamentals of Biomechanics Determine the tensions T1 and T2 in the cables, weights W, and W2, and angle a that cable 1 makes with the horizontal, so that the leg remains in equilibrium at the position shown. Answers: T1 W1 = 223.6N T2= W2 = 282.8N a= 26.6° Problem 4.10 Consider the uniform, horizontal cantilever beam shown in Fig. 4.56. The beam is fixed at point A and a force that makes an angle B= 63° with the horizontal is applied at point B. The magnitude of the applied force is P=80 N. Point C is the center of gravity of the beam and the beam weighs W = 40 N and has a length 1 = 2 m. L. Fig. 4.56 Problem 4.10 Determine the reactions generated at the fixed end of the beam. Answers: RAr=36.3N (+x) RAy=111.3N(+y) MA=182.6 Mm (ccw) %3D %3D Problem 4.11 Consider the L-shaped beam illustrated in Fig. 4.57. The beam is welded to the wall at point A, the arm AB extends in the positive z direction, and the arm BC extends in the negative y direction. A force P is applied in the positive x direction at the free end (point C) of the beam. The lengths AB and BC are a and b, respectively, and the magnitude a
