| چکیده | ||
| In this paper, we construct Rod and Euler Bernoulli Beam equation which the fundamental mode and the physical parameters are polynomial. Also for a class of Beam equation that the product of the linear mass density and the second moment of the cross-sectional area is constant, we approximate the physical parameters by Lagrange interpolation polynomial and construct them with one fundamental mode. | ||
