modulus E and the cross- Derive element equation for a 2-node finite

modulus E and the cross- Derive element equation for a 2-node finite element if both elastic sectional area A vary linearly as E = {(1 L) (1 + L) and A - 1(1 L) (1 + L where Aj, Az and E, Ez are the values at nodes 1 and 2, respectively. Assume constant body force per unit volume and constant surface traction per unit length.
