The attachment below shows a structure ABC where AB=3 m, BC=2 m. Both these parts have the same value for E and I which are 210 000 MPa and 2*10^6 mm4. A force of 5 kN acts as shown. Do not consider axial deformation. I am to find both the vertical and horizontal diplacement of point C. My first idea here was to flip the structure 90 degrees to the right and then consider AB as a cantilever beam which would now be acted on by a torque created by the force. A formula for calculating the downward displacement for such a beam is:(adsbygoogle = window.adsbygoogle || []).push({});

\delta = \frac{{M \cdot l^2 }}{{2EI}}

With inserted values I get 107 mm, which sound realistic to me at least but correct me if it isn't. But now I'm completely stuck when it comes to finding the vertical displacement. What should I now do?
