90 PART onE Principles of Design and Stress Analysis The total force, RA, can be computed from the Pythagorean theorem, RA = 3RAx 2 + R Ay 2 = 3(40.0)2 + (26.67)2 = 48.07 kN This force acts along the strut AC, at an angle of 33.7° above the horizontal, and it is the force that tends to shear the pin in joint A. The force at C on the strut AC is also 48.07 kN acting upward to the
