If two loads are applied to a cantilever beam as shown in the accompanying drawing, the bending moment at 0 due to the loads is a,X, + a,X2.

2. Muscle A and muscle B are attached to a bone as indicated in the figure below. Muscle A exerts a force on the bone at angle a, while muscle B exerts a force on the bone at angle ß. Muscle B Muscle A Bone a. Assume muscle A exerts a force of 900 N on the bone at an angle a = 8°, while muscle B exerts a force of 75O N on the bone at an angle of B = 33°. Find the resultant force and the angle of the force due to muscle A and muscle B on the bone. b. Assume muscle A exerts a force of 1000 N on the bone at an angle a = 9°, while muscle B exerts a force of 820 N on the bone at an angle of ß = 38°. Find the resultant force and the angle of the force due to muscle A and muscle B on the bone.

a b B C A FIGURE NOT DRAWN TO SCALE! Two structural members B and C are bolted to bracket A. Knowing that both members are in tension and that P=12.3 kN and Q-20.1 kN. For a=2 deg and b=67.7 deg, determine using: a) the law of cosines and the law of sines: 1- the angle opposite from the resultant force (in the drawn triangle, used to find the resultant force) in deg.
