he load is supported by the steel wires that are connected to the rigid members AB ar etermine the vertical displacement of the 600-lb load if the members were originally hen the load was applied. Each wire has a cross-sectional area of 0.025 in² and use E or steel. E H TH1.5 f 1.8 ft 2.5 ft -4 ft- F 3 ft G +1 ft- 600 lb 5 ft B

The beam is 30% glass-reinforced plastic, the triangular load is w0 = 300 lb/ft  and the factor of safety is 10. The support at A is a pin and the support at B is a roller. the beam will fail due to bending and not shear, determine the required value of b

Answer should be 40 ft please explain so I can understand

Please solve The force in member EF using methyod of section. (Solve it fast)

(c) The rigid bar ABC is suspended from three wires of the same material. The cross- sectional area of the wire at B is equal to half of the cross-sectional area of the wires at A and C. Determine the tension in each wire caused by the load P shown. ----|--²--| A 9 DAB T L P Fig. Q1(c) PL Hint: S = note that ABC is a rigid bar. EA C
