Question

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

distributed body force given by fx0 ¼ 0 and fy0 ¼ erg where r is the density of the material and g is the acceleration

due to gravity. Assume the value of r as 2800 kg/m3 and g ¼ 981 m/s2

. 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
