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.
