This paper deals with the existence of positive solutions for the fourth-order nonlinear ordinary differential equation subject to the boundary conditions: where Ξ±, Ξ², Ξ³ , Ξ΄ β₯ 0 are constants such that Ο = Ξ±Ξ΄ + Ξ±Ξ³ + Ξ²Ξ΄ > 0, and ΞΎ i β (0, 1), By means of a fixed-point theorem due to Krasnaselskii,
