Use Superposition method, beams' formulas table, and$/$or direct integration method $($if needed$),$ to find the deflection and slope at point C$.E=29{10}^6.$

Consider Also draw bending moment and shear force diagram weight of the beam as per the section tabla $($Uniform load$)$

Tip: this is an indeterminate beam, you need to find the reactions first and then find the slope and deflection.

L $=107$

P $=1532$
