The document discusses beams supported on two supports. It contains 5 topics:
1) A beam carrying a concentrated central load.
2) A beam carrying eccentric central loads.
3) A beam carrying a uniformly distributed load.
4) A beam carrying a triangular load.
5) A beam carrying a combination of loads.
The purpose is for students to understand internal forces (bending moment and shear force) in beams supported on two supports under different load conditions and to calculate and illustrate them. Detailed calculations are shown for each load condition.
