WebJun 4, 2024 · This leaves only three reactions left in the two pin-joints which can be found using three equations of statics: ∑ F x = 0, ∑ F y = 0, ∑ M = 0. These will find the three reactions which will lead to the axial forces in the bars which can then be used in the axial stress and euler-buckling formulas respectively.
