2. Calculate Young's modulus from the following data: Load on the Readings of the scale (cm) Change in the reading hanger (gm) when the load is Average s of the scale when the load is increased by increased (S;) decreased (Sd) M = gm 100 8.4 8.5 300 6.2 6.3 54 - 51 -X1- 500 3.9 4.0 $5 - $2 = X2 = 700 1.7 1.8 56 - 53 - X3- 900 -0.5 -0.4 1100 -2.7 -2.6 Average x = Average diameter of the wire = 0.036 cm Average length of the wire = 96.7 cm Average diameter of the cylinder = 1.24 cm Average distance between the mirror and the scale = 84.6 cm
