for the flat truss structure (bar support structure) above.
A model of a truss with section length L = 2 m is built up of 13
rods. The rods are connected via torque-free joints. The weights of
the rods are negligible compared to the loads applied. All rods are
made of steel which can be considered as a linear elastic-ideal
plastic material with the E-module E = 200 GPa and the yield stress
σs = 250 MPa. The truss can only be deformed in the
plane. The truss is loaded in the points 4 and 7, where P = 50 kN.
The rods 1, 2, 5, 7, 10, 12, 13 have the cross-sectional area
2A0 while the other rods have the cross-sectional area
A0. Solve the following questions using python:
