Practice session

A beam ABCD has a total length of 6.0 m. It has a pin support at B (x = 1.0 m) and a roller support at C (x = 5.0 m), leaving 1.0 m cantilever overhangs AB and CD. Downward concentrated loads of 10.0 kN and 6.0 kN act at the free ends A (x = 0) and D (x = 6.0 m), respectively. A uniformly distributed downward load of w = 5.0 kN/m acts along the 4.0 m span BC. What are the vertical support reactions at B (Rb) and C (Rc)?
