Hi there! Can anyone take me through the method of joints procedure for this truss? I am having trouble working out the reaction forces at the pin at joint A. Is there supposed to be a vertical component to the reaction force as well a a horizontal (seeing as it is a pin)? And if so where does it go? is it part of the member AD or outside of it? I am confused. P.S. The answers are AB = 5 kN T, BC = 5*sqrt(2) kN C, CD = 15 kN C, AC = 5*sqrt(2) kN T, AD = 0. Where T = tension, C = compression.
