Draw sketches of at least two sections each where (i) section modulus is the same and (ii) section moduli are different, with respect to top and bottom fibres.

Find the MI of an isoceles triangle of base 200 mm and height 300 mm about an axis through its base and a parallel axis through its centroid.
