Statement F XL- (1) A rod with a length L = 1.8 m is free to rolate around a Of its ends. Three forces act on the rod, other than at the pivot, al and are represented in the figure. The F3 force acts in the center of the rod. If F, = 8.6 N, F2 = 4.0 N, Fg = 9.6 N, a = 35, B. B = 31 and x = 0.25, what is the moment of force of each force?Statement (1) A person holds a mass of 6 kg in his hand, his forearm making an angle of 0 = 16 downwards with respect to the horizontal. The biceps (flexing muscle of the elbow) is fixed at d = 5 cm from the joint and acts at a = 50 with respect to the vertical. The forearm is assimilated to a homogeneous rod of negligible thickness, mass 1 kg and length L = 35 cm. (a) What is the tension module in the biceps? e (B) Determine the modulus of the horizontal and vertical forces exerted by the elbow joint on the forearm. LStatement () A human bone has a Young module of 1010 N/m? About. It fractures when the compression deformation is greater than 1.1%. What is the maximum load, in kilograms, that a bone with a cross-section has an area of 3.2 cm2 can withstand?(1) The masses and positions of four particles in the xy plane are as follows: m = 2.3 kg in (- 4.9 m, 4.3 m); m2 = 1.4 kg in (3.4 m, - 1.2 m); mg = 1.1 kg in ( - 1.9 m, - 3.8 m) and m4 = 4.4 kg in (4.5 m, 3.3 m). What is the position of the CM?Statement (1) A raft of dimensions 2.7 m by 2.7 m by 0.17 m is made of wood with a density p=611 kg/m?. For what uniformly distributed load (in kilograms) will the raft be immersed at 75% in water
