Introduction The purpose of this lab is to test Hookes law the law of elastic limit that states that the amount of stretch of something is directly proportional to the force applied The test will be conducted by placing weights on the end of various springs and measuring their stretch If the most weight is placed on the largest spring then it will stretch the most ProcedureMaterials Materials needed - Ring standsupport tower - 3 springs of carious sizes - Paper clip - Masking tape - Meter stick - Set of slotted masses - Large rubber band - Graph Paper Procedure 1 We first hung one of the springs doesnt matter which one from the paper clip which was hung from our support stand There was a measuring stick on the support so we did not use the meter stick 2 We then measured where the end of the paperclip rested and used that as our theoretical zero 3 We then attached different masses to the end of the spring After every time we added a mass we measured where the paperclip was resting and recorded the mass in kilograms and stretch in meters into our data table 4 We then repeated steps 1-3 for the other springs and the rubber band 5 After we completed steps 1-4 we calculated the force of each mass by multiplying the mass in kilograms by 984 ms the earths gravitational pull to get the force of each mass in Newton meters 6 We then graphed the force y-axis vs stretch x-axis 7 After graphing the lines we found the spring constant for each spring by finding the slope of each springs graph Data and Calculations MassForceStretchSpring Constant Spring 14 kg392 N005 M1000 54901 6588015 7686023 878403 9882037 Spring 27 kg686 N003 M2125 7784006 988201 198013 111078015 121176018 Spring 302 kg196 N003 M2500 04392009 06588015 08784021 198027 121176033 Rubber Band02 kg196 N001 M1000
