  1. When a rubber strip with a 3 by 1.5 mm cross section issuspended vertically and various masses are attached to it, astudent obtains the following data for length versus load.

   Load(g):          0       100    200    300    400   500

Length (cm):    5.0     5.6      6.2    6.9     7.8    10.0

  1. Find Young’s modulus for the rubber strip for small loads.
  2. Find the energy stored in the strip when the load is 150 g.(Hint the energy can be given by U = (1/2)FΔL where F = force and ΔL is change in length)
