QUESTION:

The distributed loading is applied to the rigid beam, which is supported by the three bars. Each bar has a cross-sectional area of \(0.75 \mathrm{~in}^{2}\) and is made from a material having a stress–strain diagram that can be approximated by the two line segments. Determine the intensity of the distributed loading w that will cause the beam to displace downward 1.5 in.
