Q8: An electric light fixture weighing 200 N is supported as shown in Figure. Determine the tensile forces in the wires BA and BC. Use Parallelogram Method, 50⁰ 65° B 200 N حه B كروب A

All the tension/compression members of the frame structure shown in the figure are pin-jointed and of equal length and negligible weight. An external load P 34.7 kN is applied vertically at joint E. The frame is pin-connected at fixed support A and supported by a roller at D. What is the force in member AE? Input your answer as a value only in KN to one decimal place without +/- sign. A E

The force of a beam is shown in the figure below. If you want to apply an additional force of MA to make the corner of point A zero, try to calculate the magnitude of the bending moment MA, and the EI of the entire beam section is constant.

Solve the problem by the moment-area method. The beam has constant flexural rigidity EI. A simple beam AB supports two concentrated loads P at the positions shown in the figure. B C 4. 4 A support C at the midpoint of the beam is positioned at distance d below the beam before the loads are applied. Assuming that d = 12 mm, L = 5.4 m, E = 200 GPa, and I = 193 x 10° mm, calculate the magnitude of the loads P (in kN) so that the beam just touches the support at C. 163.87 x kN
