Answer:
0.719m
Explanation:
if the load/ deflection curve of the spring has Force (N) on the y axis and Deflection (m) on the x axis then the slope of the curve is 85 N/m
The energy is the area under the curve ie Base x Height/2
Area (22) = Deflection x (Deflection x 85) /2
Therefore, Def = Sqrt(22 x 2 /85)
