a) The truss on the right has Young's modulus 2E b) What is the solution of the moduli are the same V. Fyl 12, Fy2 0-2 021 Ml 2 M 53 Problem 2.5-6 Problem 2.5-7 2.5-7 Displacements of the two-member truss shown are confined to the plane of the fig- ure. Both members have A, E, and L. Obtain the 2 by 2 stiffness matrix that operates on horizontal and vertical displacements of the top node. Solve for these displacements, and for axial stress in members, when downward load P is applied.
