Homework Help: Material selection based on either U1 or U2 merit index

  1. Nov 15, 2016 #1
    1. The problem statement, all variables and given/known data
    Choose a component based on either U1 or U2 merit index and select what you believe to be the optimum material.

    2. Relevant equations
    U1=(σ)^2/E (Energy density)
    U2=(σ)^2/(Eρ) (specific energy density)

    3. The attempt at a solution

    I was going to use a spring damper from a bike as the component and apply U2, however are there any other more interesting examples I can use the merit indexes on?
