(10 points) Problem Statement: A rectangular bar of width w 10 mm, thickness t 4.5 mm, and length L-100 mm, is pinned at both ends as shown in the figure. Use theoretical values of C. Yield strength Sy-280 MPa. Modulus E-207 GPa. In-plane means deformation in the x-y plane. Out-of-plane means deformation in the x-z plane. Calculate: the load required to yield the bar Py the in-plane critical load Per the out-of-plane critical load Pcr the slenderness λ of the column in the direction it is actually buckling (in-plane or out-of-plane) . the Johnson's critial slenderness 21 the actual critical load Pcr accounting for interaction (if any) Hint: Answer tolerance-2%. Be sure to include units and the correct sign with your answer Your answers: Pcr Per
