NEXT lesson_4mar

Complete superposition tutorial
Hint Q17:
Each particle move wrt to the dotted line.
1st : x=0
2nd : x=+ve
3rd: x=amplitude
4th: x= +ve
5th: x=0
a)Plot this displacement values in Fig. B and continue until the last particle.Line Y
b) In Fig. B graph , draw the displacement T/2 later and Label it Z. (180 deg out of phase with Y.
c)See the line Z which is displacement of the particles and locate the positions in the Fig A . If positive to the right of equilibrium line, and negative to the left of equilibrium. Zero will remain as it is. Adjust the magnitude according to the graph of Z.
d) On fig C ,locate the highest excess pressure to the location where the particle as closest to each other. Lowest excess pressure to be the location where the particles are furthest apart.
