WebAssumptions The beam is long and thin (i.e. L >> h) The beam cross-section is symmetrical with respect to a longitudinal plane (x-y plane); this plane is called the plane of bending. Material obeys the Hooke’s Law. The deformation of the beam is small, linear and elastic. WebShort beams do not flex much and their deflection is due mainly to shear, not moment. A beam is said to be short if its length is less than 10 times its section depth1. This situation is covered in advanced courses. 2. Local buckling and rotational instability of beams which involves three cases: global buckling
