2.33 kN is not the right answer
In the structure shown, an 6-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 joiningB and D, determine the allowable load P if an overall factor of safety of 3.1 is desired.

As shown, two composite columns of steel and concrete are used to support a rigid platform. The columns are cylindrical, with a steel bar encased in concrete. The outer diameter of each column is dc = 24 cm. The steel in the left column has a diameter of dı = 18 cm. A load of P = 52 kN is applied with L1 = 1.5 m and L2 = 2.2 m. The height of the columns is h = 2.6...
