1. You want to show of your herculean strength to a group of scientists. To demonstrate this, you decide to push a cylindrical iron bar with a diameter of 1cm at both end until it has reduced to one half of its original length. The Young's Modulus of the iron bar is 211GPa

a) What compressive force will you need to apply to each end of the iron bar to achieve this?

b) What is the strain energy density of the iron bar during this compression?

c) What is the total energy stored in the iron bar if it has a length of 60cm?

Please can I get some help with this! xx
