For a truss given below, can we solve the force acting on every member? Surprisingly, yes. Here’s how. First, we have to solve the reactions on $H$ and $L$. $$\begin{align*} \Sigma M_{L} = 3Pa-4Ha = 0 \to& H= {3 \over 4} P \\ \Sigma F_{y} = H+L-P=0 \to& L={1\over4}P \end{align*}$$ Second, let’s get rid of zero-force members. For joint $D$ to be in equilibrium, $F_{DI}$ should be zero because there’s..
