A sign (mass 1700kg ) hangs from the end of a vertical steel girder with a cross-sectional area of 0.013m^2. Ignore the mass of the girder itself. The elastic modulus for steel is 2.0×10^11N/m^2.
Part A What is the stress within the girder?
Part B What is the strain on the girder?
Part C If the girder is 9.50m long, how much is it lengthened?
