A 3700 kg statue is placed on top of a cylindrical concrete (Y = 2.3 1010 N/m2) stand. The stand has a cross-sectional area of 7.2 10-2 m2 and a height of 2.0 m. By how much does the statue compress the stand?

  1. They give you Young's moduls of the concrete, Y = 2.3*10^10 N/m^2
    The pedestal area is A = 7.2*10^-2 m^2
    Use the elastic law that
    stress = (strain)*Y
    In this case,
    strain = compression/length
    Therefore
    compression = Length*strain
    = Length*stress/Y
    = Length *(weight)/[(area)*Y]

    Don't forget that weight = M g, so
    compression = L M g/[(area)*Y]
