Question

Which of the following does not apply to statically determinate structures?
1. Stresses are caused due to temperature variations
2. No stresses are caused due to lack of fir
3. Bending moment at a section is independent of cross sectional area of the components
4. Force in a component is independent of the material
5. Conditions of the equilibrium are sufficient to fully analyze the structure

Answer 1

Correct Answer - Option 1 : Stresses are caused due to temperature variations

Explanation:

A structure is said to be a statically determinate structures if conditions of equilibrium are sufficient to analyze the structure.

• In Determinate structures, bending moment and shear force are independent of properties of the material and cross-sectional area.
• No stresses are induced due to temperature changes.
• No stresses are induced due to the lack of fit and support settlement.

So, out of the given statements, option 1) Stresses are caused due to temperature variations is wrong.
