In the steel structure shown, a 6-mm-diameter pin is used at C and 10-mm-diameter pins are used at B and D. The ultimate shearing stress is 159 MPa at all connections, and the ultimate normal stress is 400 MPa in link BD. Knowing that a factor of safety of 3.0 is desired, determine the largest load P that can be applied at A. Note that link BD is not reinforced around the pin holes. (Round the final answer to three...

(16 points) Difficulty (4/5) A mechanical connection known as a clevis and pin is shown. The dimensions of the assembly are given as: a = 30 mm b = 33 mm c = 10 mm d = 18 mm t = 22 mm W = 45 mm L = 113 mm In order to avoid failure in the materials used to create the parts: -The normal stress in the pin must be limited to 680 MPa. -The shearing stress in...
The rigid structure ABD is supported at B by a 36-mm-diameter tie rod (1) and at A by a 29-mm-diameter pin used in a single shear connection. The tie rod is connected at B and C by 24-mm-diameter pins used in double shear connections. Tie rod (1) has a yield strength of 260 MPa, and each of the pins has an ultimate shear strength of 320 MPa. A concentrated load of P = 50 kN acts as shown at D....
