Q$1)$ Draw the influence lines for

The vertical reactions at supports A$,$B$,$ G and H

The shear and moment at mid span between $AB,GH$ and points $D$ and $F.$

Q$2)$ If the beam supports a uniform dead load of $35k\frac{N}{m},$ a uniform live load of $65k\frac{N}{m},$ and a

concentrated live load of $70kN.$ Develop the required load cases to obtain the maximum influence

of the following:

The vertical reactions at supports $A,B,G$ and $H$

The shear and moment at mid span between $AB,BC,GH$ and points $D$ and $F.$
