Sample questions with model answers
Every question in the paper gets a full exam-length answer in the app — organised by marks, the way a topper writes it.
Determine the centroid of area of a rectangle of breadth b and height h.
Show answer outline
The centroid is located at (b/2, h/2).

State and proof parallel axis theorem of moment of inertia.
Show answer outline
I = I_c + A*d^2, where I is the moment of inertia about any axis, I_c is about the centroidal axis, A is area, and d is the distance between the axes.

Determine the moment of inertia of a triangular lamina about its base and centroidal axis.
Show answer outline
Moment of inertia about base = (b*h^3)/36, about centroidal axis = (b*h^3)/12.
