Question #54206

Two struts (strut-1 and strut-2) have the same length L and the same end support conditions. The modulus of elasticity E1 for strut-1 is twice the modulus of elasticity E2 for strut-2. The moment of inertia I2 for strut-2 is twice the moment of inertia I1 for strut-1. If P1 and P2 are the critical buckling loads for strut-1 and strut-2, respectively, how are P1 and P2 related?
