Beams

In this part of the guide, we will count the support reactions for different types of beams.

For example, we have 3 beams consisting of various supporting elements and types of forces acting in different places on the beam. On the test or exam you can get a completely different distribution of forces or supports, but the calculation method is the same.

All three beams are statically determinate and geometrically immutable.

Simply supported beam

Straight beam supported on the left side with articulated joint and right articulated sliding. The total length of the beam is 11 meters. Two concentrated forces work on it.

Cantilever beam

Straight beam on the left side fixed by a bracket, on which the distributed force and the horizontal concentrated force are acting. The total length of the beam is 10 meters.

Continuous beam

Composite multi-joint beam. It consists of three shields. The total length of the beam is 17 meters.
