Buckling beam differential equation
Webequations for determining the value of J for common shapes are provided in the literature [2][3][6]. 1.2.1 Effect of Beam Slenderness Equation 1 was derived for slender beams where the in-plane flexural rigidity (EI x) is much larger than the out-of-plane flexural rigidity (EI y). Federhofer and Dinnik [2] found this Web3. Exact solution of buckling equation and the formulas for variables of rod’s state Equation (1) is the special case of known [11-13] differential equation of free transverse vibrations with taking into account the self-weight. EIv x qxvx pmvx () ( ()) 0 2, (3) where p the frequency of vibrations.
