Question $1$ is based on the information in Figure $1.$ A cantilever beam with a fixed support at

point A carries one UDL load of $1K\frac{N}{m}$ between points A and $C$ and, a concentrated load of

$20$ kN at point B and $2$ kN at point C as indicated in figure below:

Figure $1.$ Beam diagram.

Question $1$a$.$

Calculate the support reactions.

Question $1$b$.$

Calculate shear forces and draw the shear force diagram.

In your answer, find the maximum shear force acting on the beam.

Question $1$c$.$

Calculate the bending moments and draw the bending moment diagram.

In your answer, find the maximum bending moment acting on the beam.

Determine the location of the point$($s$)$ of inflection $($contraflexure$)$ and calculate the BM at

this point.
