The discussion revolves around the presence of horizontal force components at the hinge of a truss structure when subjected to vertical loads. Participants explore whether the design of the truss influences this horizontal component and seek clarification through diagrams and examples.
Participants express differing views on the presence of horizontal components at the hinge, with some asserting their existence and others questioning the conditions under which they arise. The discussion remains unresolved regarding the definitive impact of truss design on horizontal forces.
The discussion lacks a consensus on the specific conditions that lead to horizontal components at the hinge, and the assumptions regarding the truss design and load application are not fully articulated.
Usually there is a later component in a truss, or a diagonal element. However, I would expect some lateral element because structures are 3-D.cuddlesome said:If the loads are all vertical in a truss, will there be horizontal component on the hinge of the given truss?
Does the presence of the horizontal component depends on the design of the truss?
Yes - I would have thought that was pretty obvious looking at the diagram.cuddlesome said:Will there be a horizontal force component at A?
Thanks - I was worried that I sounded a bit condescending - then I noticed the cornel.edu address and figured this wasn't a grade4 student!FredGarvin said:Just to echo what mgb_phys mentioned
