Calculate the MR of a doubly reinforced R.C beam of rectangular section of size $300 mm {\times} 450 mm$ deep reinforced with 6 No. 20 mm dia. bars on tension side and case:-
4 no. 20 mm ${\phi}$ on comp side.
5 no. 20 mm ${\phi}$ on comp side.
Assume effective cover of 40 mm on both sides. Use $M_{20}/F_{e415}$
