Q- The system shown in the figure is in equilibrium. Mass of A is 150 Kg. Mass of B is 70 Kg. Find T1, T3 and e. \35° T1 T3 200 N 1 m 0.5 m B A

answer coherently

a) As shown in the image given, a 69-kg crate is supported at equilibrium. The angles alpha=112 degrees. beta=145 degrees and the V =64.3 degrees. The coordinates of point D are (-2.2, 5.6, 3.2)m, and the spring constant k=1170N/m. Determine the stretch in the spring, in m which must be rounded to 3 places after the decimal point. Take g=9.81m/s^2. b) As shown in the image given, a 63-kg crate is supported at equilibrium. The angles alpha=112 degrees. beta=145 degrees and the V =64.3 degrees. The coordinates of point D are (-2.4, 5.5, 3.7)m. Determine the tension force in cable AC, in N. Take g=9.81m/s^2.   c) As shown in the image given, a 64-kg crate is supported at equilibrium. The angles alpha=112 degrees. beta=145 degrees and the V =64.3 degrees. The coordinates of point D are (-2.2, 5.4, 3.2)m. Determine the tension force in cable AD, in N. Take g=9.81m/s^2.
