EGMN-103Hooke’s Law LabPennyfeather, JadariusINTRODUCTIONAccording to Khan Academy, “When studying springs and elasticity, the 17century physicistᵗʰRobertHookenoticed that the stress vs strain curve for many materials has alinearregion. Within certain limits,the force required to stretch an elastic object such as a metal spring is directly proportional to theextension of the spring.” This is known as Hooke's law. In this lab, we will test whether rubber bandsfollow Hooke’s law by conducting trials of increased forces acted upon them.OBJECTIVESTo investigate whether rubber bands follow Hooke’s LawWork with a partner.Produce a lab report which covers the work and details that were discoveredEQUIPMENT1.Five identical rubber bands2.Spring Force scale, 0-20N3.Ruler, 60 cm4.Hook (Large paper clip)5.TapePROCEDURE1.Number the rubber bands 1-5.2.Create a table with 6 rows and 9 columns in the lab notebook for rubber band 1. Title it as:‘Raw data for Rubber band 13.Insert the hook/paper clip into the hole at the end of the ruler.4.Securely tape the paper clip to the desktop.Be sure to get a picture of the apparatus.5.Adjust spring scale so that it reads zero.6.Stretch the first rubber band to its maximum length (~45 cm) and hold for 5 seconds.7.Repeat the stretching 10 times.8.Loop the rubber band around the paper clip hook and the spring force scale.9.Draw the rubber band out to its full ‘zero force’ length. Take a measurement at the end of thepaper clip (P0) and where the far end of the rubber band reaches (S0) and record in notebook.Read the ruler as mm and read to the nearest 0.1 cm.10.Pull the spring scale force to 2 Newtons and record the S2 length in your notebook.11.Pull the scale to 4 N and record the length (S4)12.Do the same for S8, S10, and S12.13.Repeat these measurements with the same rubber band in order from 0-12 N a total of 5times.14.Take the first rubber band off of the paperclip/hook.15.Create another table in the lab notebook for the second rubber band. Title the graph ‘Raw datafor Rubber band 2.’16.Place the second rubber band onto the hooks and continue the experiment by taking itsmeasurements according to instructions 3 - 14. Do the same with rubber bands 3-5, perinstructions 3-14.
