Homework Help: Stress and strain

  1. Oct 27, 2008 #1
    A marble column of cross-sectional area 1.5 m^2 supports a mass of 2.5×10^4 kg.

    What is the stress within the column?
    What is the strain?

    I have already found the stress in the column by taking (25000kgx9.8 m/s^2)/1.5m^2
    The problem is i have no clue how to find the strain given this information. I know strain is delta Y/ original length, or strain/youngs modulus.

    Without any information regarding its length or Young's modulus, you can't find the strain.
