Unformatted text preview: The sum of the forces must be zero, which means that the force triangle must close; therefore, I have drawn the forces long enough to do so. Using the Law of Sines, Now I compute the normal stresses. .. Next, I find the shearing stresses in the pins. .. Note that a factor of two was used in each denominator since both pins are in double shear. The bearing stress in member BC at C is:...
