Chapter 1, Problem 1.55(choose chapter or problem)
In the structure shown, an 8-mm-diameter pin is used at A, and 12-mm-diameter pins are used at B and D. Knowing that the ultimate shearing stress is 100 MPa at all connections and that the ultimate normal stress is 250 MPa in each of the two links joining B and D, determine the allowable load P if an overall factor of safety of 3.0 is desired.

QUESTION:
In the structure shown, an 8-mm-diameter pin is used at A, and 12-mm-diameter pins are used at B and D. Knowing that the ultimate shearing stress is 100 MPa at all connections and that the ultimate normal stress is 250 MPa in each of the two links joining B and D, determine the allowable load P if an overall factor of safety of 3.0 is desired.
ANSWER:
Step 1 of 14
We have to find the allowable load P for the given structure. We will find the allowable load by considering three cases. (1) shearing stress in pin at A.(2) shearing stress in pin at B and D. (3) Normal axial stress in link BD Minimum of the three will be allowable load
