The figure shows a pin-jointed plane truss Ioaded at the point M by hanging a mass of 100 kg. The member LN of the truss is subjected to a load of

1. 0 Newton
2. 490 Newtons in compression
3. 981 Newtons in compression
4. 981 Newtons in tension

Consider all forces at point L

Summation of all forces along x-direction, F_LK = F_LM
Summation of all forces along y-direction,
F_LN = 0
