right ends and the concentrated forces at lower nodes of the model
can be applied conveniently as shown in the figure.
Once the problem has been set up, solutions of the
deformed shape and stresses in the beam members can be obtained
without difficulty as shown in the figures. The figures show the
deformation shape and stresses that occur in these beam members.

3.4 Application

3.4.1 Racing Car Frame Structure

A racing car frame structure is made from structural
3
steel material that has the density of 7,850 Kg m , the Young’s
modulus of 210 N m 11 2 and the Poisson’s ratio of 0.3. The
engine and driver weights, as shown in the figure by the spheres at
the front and middle of the frame structure, are 10 and 75 Kg,
respectively. The deformed configuration and member stresses are
to be determined when the forces from the weights are triple,
simulating while the structure drops into a road pit-hole. We will
use ANSYS through the Workbench to analyze the problem.
