(IMAGES PROVIDED BELOW)

Find the area bounded by the curve or graph and the two axes on the maximum point plotted. What does this area represent? Check this area by the equation W=1/2kx where k=force constant and x=the total extension. Area enclosed = W =1/2kx2= REMARKS AND CONCLUSIONS QUESTIONS AND PROBLEMS 1. The force constant of a spring is 5.51b. Per inch. How much work is done in compressing the spring 2.5 inches? 2. A steel wire 1000 ft. long is half (500 ft.) of 1/8 inch wire and half 3/16 inch wire. The whole is stretched 4.5 inches. How much is the elongation of each half? 3. A spring 8" long stands vertically. It has a force constant of 20 1b. per inch. A weight of 28 lbs. drops vertically on the spring and shortens it by 2.8 inches. From what height does the weight drop? ANSWERS:OBJECTIVE: To verify Hooke's Law of elasticity as applied to spring.
