How to calculate Young's Modulus for flat spring

  1. Oct 27, 2015 #1
    Hi, I have a question regarding calculating Young's modulus for a flat spring. I have a flat spring shown as the left one in the image. Now I fix the bottom of the spring and exert a force F on top of it and it bends for distance of d. Is there any way to calculate young's modulus for this spring? I searched online and found a method called Three point flexural test , but looks different from my case. Thank you.

    Look up deflections of cantilever beams.

    Thank you Chet, your answer solves my problem. Many thanks.

    I also found Euler–Bernoulli beam theory, which is also very useful.
