1. The linkage system below consists of two bars A & B plus 4 linkages. Each linkage has a square cross section. The allowable tensile strength of all members is 200 MPa, the allowable bearing stress for all members is 140 MPa.
a. Considering bearing stress between the 5 mm diameter pins and the linkages, determine the maximum allowable load P.
b. Considering the tensile strength of bar A, what is the maximum allowable load P.
c. If P = 10 kN, determine the maximum allowable diameter of the large pin in bar B.
