When is a truss rigid

Below is the figure for reference:. Start Learning. This question was previously asked in. Determinate structure Geometrically unstable structure Statically unstable structure Structurally unstable structure.

Start Now. Explanation The stability or instability of a truss depends upon the loading conditions it is facing. Steps to check the stability of a truss: First, calculate the degree of static indeterminacy.

All the reactions are concurrent. Important Points a Below are the figures for the references: For this particular loading pattern, the non-triangular truss structure is stable.

If a horizontal load is introduced in the above truss arrangement, it will become unstable. There is no reaction to balance H force, hence the above truss is unstable.

The simply supported beam shown in the figure. For a skeletal frame shown in the figure Static and kinematic indeterminacies are.

A rigid-jointed plane frame is stable and statically determinate if -. The degree of static indeterminacy of the frame shown in the following figure is. How is a truss, which undergoes rigid body translation for an arbitrary load, classified as? If the forces in the members of a structure as well as the reactions can be found by the conditions of equilibrium, then it is known as.
