To draw SFD and BMD for simply supported beam under UDL of 10KM/m, follow these steps:

• Calculate the reactions at the supports

• Draw the SFD by taking the upward forces as positive and starting from one end

• Draw the BMD by taking the positive moment as clockwise and starting from one end

• Mark the maximum values of SFD and BMD

• Check the equilibrium and compatibility of the beam

Precommissioning tests of transformers ensure proper functioning and safety before energizing.
