Please show each and every step while solving. Thanks!

Determine the (equivalent) nodal forces for the quadratic varying
pressure loading (p(x)=ao+ ax+ ax³) shown in the Figure below.
p(x)
P3
P2
Hint: There are three CST elements (1, 2, and 3) in the system;
the side 1-2 in element (1), and the side 2-3 in element (3) are subjected
to the quadratic pressure p(x). First determine the function p(x), and then
use the method discussed in class to determine the equivalent (element)
nodal forces at nodes 1 and 2 for the first element, and then those at
nodes 2 and 3 for the 3rd element (node #2 is common between
elements 1 and 3).
