Measuring Young modulus of copper

... Physics TAS Full Report D1:Measuring Young modulus of copper 19-10-2006 Aim -To show that solid matter (copper wire) obeys Young modulus by finding the relationship between the load which is loaded at the end of the wire and extension of the copper wire. -To show that solid matter (copper wire) obeys Hooke's law in elastic deformation condition. Apparatus Copper wire Slotted mass with hanger (0.1kg each) G-clamp Adhesive label Wooden blocks Micrometer screw gauge Half-meter ruler Safety goggles Pulley on clamp Procedure 1. A micrometer screw gauge is used to measure the diameter d of the wire at 2 or 3 different points along its length and is taken the mean value. 2. The apparatus is set up on the bench as shown above. Be fixed an adhesive label on the wire as a marker. 3. Original length l of the wire from the wooden blocks to the marker is measured before be added slotted mass to the wire. 4. The wire is loaded in steps and be recorded
