calculating the reaction forces:




The pin support at A is replaced by two reaction forces in horizontal and vertical directions whereas the roller support at B is replaced by a single reaction force in vertical direction. The uniformly distributed load(UDL) of 2kN/m is replaced by a point load of 10kN that acts at the center of its application which is 2.5m from the A.





sign convention
upward:+ve
downward:-ve
right side:+ve
left side:-ve
clockwise:-ve
counterclockwise:+ve

considering the equilibrium condition of the beam.
