For the following problems, use the following structure: Note: The pin at A is in single shear, and the pin at B is in double shear. The rods are all to be of square cross-section. The members are made out of a material with σ = 15 kip/in, meaning maximum allowable for either tension or compression. The pins are all made out of a material with τa = 10 kip/in.
Problem 1: For members BC and CD, what are the minimum cross-sectional dimensions of the square rods rounded up to the nearest 1/8 inch, meaning 1/8, 3/8, 5/8, etc.?
Problem 2: For the round pins at A and B, what are the minimum diameters of the pins rounded up to the nearest 1/8 inch, again, meaning 1/8, 3/8, 5/8, etc.?
