A long construction member of uniform section is to be lifted using ropes at $C$ and $D$ ( see Fig. 10.12 (a)). This

causes bending moment due to self weight as shown in Fig. 10.12 (b). To minimise the peak value of bending moment,

the overhang $' b ‵$ shall be such, that

- 1
  
  $M_{2} = 0$
- 2
  
  $M_{1} = M_{2}$
- 3
  
  $M_{2} = 2 M_{1}$
- 4
  
  $b = \frac{1}{4}$
