Urgent.

P = 18 kN

A frame is built with members ACB and DC to support load P as shown. Member DC has a rectangular cross section with width of 25 mm and thickness t. Stress-strain curve for the material of which the member DC is made is also provided below. a. Determine the thickness t so that member DC does not yield. (You can assume same behavior for compression and tension) b. Determine the diameters of the pin A and D if allowable shear stress for pins is Tall = 40 MPa. 550 500 - - 200 mm 200 mm 450 - B. 400 - 500- 350 400 300 - 200 mm 300- 250- 200- 200 - 150 - 100- 100어 150 mm 100 - 0.002 0.006 0.004 Engineering Strain (mm/mm) 0.010 0.d00 0.008 25 mm 50 - D 0.00 0.02 0.04 0.06 0.08 0.10 0.12 0.14 0.16 0.18 0.20 0.22 Engineering Strain (mm/mm) Stress-strain diagram for member DC in Question 1 Engineering Stress (MPa) Engineering Stress (MPa)
