Using the three-noded bar element shown in Figure P10-5 (a) and (b), with shape functions given by Eq. (10.5.9), determine

(a) The intrinsic coordinate s at point A and

(b) The shape functions, N1, N2, and N3 at point A. For the displacements of the nodes shown in Figure P10-6, determine

(c) The displacement at A and

(d) The axial strain expression in the element.
