What will be an ideal response?
Problem 1.69 The two portions of member AB are glued together along a plane forming an angle ? with the horizontal. Knowing that the ulti¬mate stress for the glued joint is 2.5 ksi in tension and 1.3 ksi in shear, determine (a) the value of ? for which the factor of safety of the member is maximum, (b) the corresponding value of the factor of safety. (Hint: Equate the expressions obtained for the factors of safety with respect to the normal and shearing stresses.)
