Based on Figure 1, we get:
In matrix form, the above can be re-written as:
Calculate k1, δ2, and f3.
Based on Figure 2, we have:
The system stiffness matrix is:
Therefore, the problem becomes:
Which in turn results in the 3×3 system of equations:
Finally, we get:
The rod of the picture is loaded with the force 2...
Calculate the maximum allowable shear force Vmax...
