Assumptions made in theory of simple bending
Following are the assumptions made in theory of simply bending
- The material of the beam is perfectly homogeneous.
- The beam material is stressed within its elastic limit and thus obey’s Hooke’s law.
- The transverse sections which are plane before bending, remain plane after bending also.
- Each layer of the beam is free to expand or contract independently of the layer, above or below it.
- The value of Young’s modulus for the material of beam is same in tension and compression.
