Question

For the rectangular element considered in Problem 10.52 and Fig. 10.35, find the element nodal force vector due to

uniform surface tractions, with Fx0 ¼ 1000 Pa and Fy0 ¼ 500 Pa, applied on the edge (face) ij. Perform the

needed integration by evaluating the integrand at the centroid of the element and treating the integrand as a constant

throughout the element.

Answer 1

N=$\frac{y}{H}-\frac{xy}{LH}$

=0.25*1000+ 0.25*500

=375
