Homework Statement
A marble column of cross-sectional area 1.7 m2 supports a mass of 30,000 kg.
(a) What is the stress within the column?
(b) What is the strain?
Elastic modulus for marble E (N/m^2) 50e9
shear modulus (G)
Homework Equations
a)stress=F/A=N/m^2
b) don't know
The Attempt at a Solution
a) 30000*9.8/1.7=172941 N/m^2 (this is right)
b)
