Assume the beam is bending on a horizontal frictionless plane.

a$.$Draw a stress element at point A $($x$=2\mathrm{.}5$m and at the neutral axis of the beam$).$ Write down the values of the stress components.

b$.$Draw a stress element at point B $($x$=3$m$,$ y$=0\mathrm{.}05$m$).$ Write down the values of the stress components.

c$.$Plot the deflection of the beam as a function of x
