NOTE$($S$)$:

a$)$ Read the Question completely. The points for each sub$-$question are also provided.

b$)$ In the influence line diagram, clearly indicate the force function and its units in the $y-$axis. Also, clearly mark the values of the $y-$coordinate corresponding to each of the critical points $A$ to $H$

c$)$ Neatness COUNTS

Use the M$$ller Breslau Principle to draw the Influence lines for the beam given, and for the force functions given below. The sub$-$points for each influence line$/$category are also provided:

Provide the following:

Points

a$)$ Influence line for vertical reaction at support $A$

$5$

b$)$ Influence line for vertical reaction at support $B$

$5$

c$)$ Influence line for Shear at D

$5$

d$)$ Influence line for Moment at D

$5$

e$)$ Influence line for Shear at $F$

$5$

f$)$ Influence line for Moment at $F$

$5$

g$)$ Influence line for Shear just to the right of $B$

$5$

h$)$ Influence line for Shear just to the left of B

Calculate the maximum shear developed at $F$ due to a moving distributed load of $5k\frac{N}{m}.$ Assume the distributed load covers the entire beam

Calculate the maximum positive reaction developed at support A due to a moving distributed load of $5k\frac{N}{m}$ and a moving concentrated load of $25kN.$
