Test No. VNL11Find the critical compression load at
which a simply supported beam buckles.
Definition
A simply supported beam is subjected to a compression load.
The units are SI.
Figure 1.
Dimensions: L = 965 mm, b = 40 mm, h = 40 mm
Where,
- b
- Breadth of the rectangular section.
- h
- Height of the rectangular section.
The material properties are:
- Properties
- Value
- Modulus of Elasticity
- 2.1e11 pa
- Poisson's Ratio
- 0.3
