An overhanging beam of overall length $L$ and uniform flexural rigidity $E I$ is loaded by two concentrated loads at the two

ends. The beam is supported symmetrically on two supports with overhang $' a ‵$ on each side as shown in Fig. 10.18.

The vertical deflection upwards at the centre of the beam is given

- 1
  
  $P a {(L - 2 a)}^{2} / 8 E I$
- 2
  
  $P a^{2} (L - 2 a) / 8 E I$
- 3
  
  $P a L^{2} / 8 E I$
- 4
  
  $P a^{2} (L - a) / 8 E I$
