From the Hooke law, stress s is proportional to strain e; s = Ee where E is elastic modulus of the material; the stress is the bending stress which varies from plus on one surface to minus on the opposite surface.
Think of stress as bending or pushing down upon an object, where as strain is more like stretching a rubber-band almost to its limit, or the stress of a bridge holding up.
1. Plane sections normal to axis remain plane after bending. This implies that strain is proportional to the distance from neutral axis. 2. Maximum strain in concrete of compression zone at failure is 0.0035 in bending 3. Tensile strength of concrete is ignored. 4. The stress-strain curve for the concrete in compression may be assumed to be rectangle, trapezium, parabola or any other shape which results in prediction of strength in substantial agreement with test results.
There is a small logic we can calculate the load capacity,for that we need Stress and Strain formulas, shearing moment and bending moment, from that we can know where the system fails and works........ DR.....
Assumptions The beam is symmetrical about Y-Y The traverse plane sections remain plane and normal to the longitudinal fibres after bending (Beroulli's assumption) The fixed relationship between stress and strain (Young's Modulus)for the beam material is the same for tension and compression ( σ= E.e )

Line bending or "strip heating" is a form of bending plastic.
A knee strain is an acute injury in which tendons and ligaments become stretched or torn. Most strains occur because of direct blows to theknee, extreme bending or twisting of joints, or overuse through repetitive activity. The most common symptoms include pain, swelling, loss of mobility, and a lack of strength. Depending on the severity of a knee strain, an individual may be able to ease symptoms and recover with rest and simple home remedies. A serious strain usually requires immediate medical attention, surgery, and several weeks of physical therapy.
