Yes it worked! Thanks a million!

Joint e ?

The whole structure would "flatten" and be pushed to the right?

No, it would collapse.

The horizontal component of the reaction force would be zero as it free to move in this direction on the end support, right?

Yes exactly, I noticed that I can obtain the fourth equation from the first three so I need a fourth independent one. But I'm under the impression that it is a single structure, I guess I'm wrong!

Homework Statement I'm having a hard time finding the support reactions R_{fx} ; R_{fy} ; R_{kx} ; R_{ky} in this truss. 2. The attempt at a solution I got four equations using the equilibrium conditions (sum of forces along x and y ; sum of moments on F and on C) but the system doesn't...

We all know that the geometrical foundations of general relativity follow riemann's geometry and not the euclidean one. About 3 months ago a lebanese mathmaticien claimed that he proved the 5th postulate of the euclidean geometry (about the parallel theorem) which is still with no proof...

Lately the number of scientists against the big bang theory is increasing for lots of reasons espacially the growing number of hypothetical entities like dark matter, dark energy and inflation which scientists were not able to observe but only to predict by the analysis of backround...
