Question

Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE.

The frame, loaded as shown, is pin-supported at A using two support plates and at B using one support plate. There are two members EF connecting members ACE and BDF. Members ACE and BDF have a width of 5 in and thickness of 1.5 in, while members EF and CD have a width of 4 in and thickness of 2 in. The support plates at A and B are 1.75-in-thick. Using a factor of safety FS, determine the range of values for the diameter of the pins based on the following known stresses at failure:
• normal stress of 100 ksi for link EF,
• shear stress of 150 ksi for pins A, C, and E, and
• bearing stress of 80 ksi for member ACE and the support plates at A and B.

All pins are identical. Express your final answers to the nearest 1/16 of an inch.
