(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The triangular plate weighs 80N, is articulated to the bars AH and EF (negligible weight) through joints in the points H and D respectively.

Determine the horizontal reaction at support A using the principle of virtual work.

2. Relevant equations

Work=0=Sum Force*Displacement + Sum Moments* d Theta

3. The attempt at a solution

Try to find the displacements, but I want to know the quickest way for solve this problem.

Any recommendation on how to solve this problem more efficiently, be grateful.

Thanks
