Tensile Strength of Different Types of fishing Line Problem What material will have the highest tensile strength? what are the options? Ms. Miller Background  Tensile strength is the maximum pulling stress a material can withstand before failing or breaking. Tensile strength is actually very important when it comes to the design of many materials. If the tensile strength of fishing line is to (sp)  low, it will break when trying to catch a fish. Concrete is used in building and the tensile strength needs to be perfect to insure the stability of the building. Tensility is akin to ductility, a metal's ability to be drawn into a wire. When a ductile metal is put under tensile stress, it will neck ??? . Tensile strength is generally measured in newtons(N). An important factor in determining tensile strength is cross sectional area. The cross sectional area is the two dimensional area of a three dimensional area of an object. For instance, the circle on a cylinder. Cross sectional area is directly proportional to the tensile strength of an object. The higher the cross sectional area, the higher the tensile strength.  Fishing line is an important material for fishing. There are many kinds of fish and thus, many different kinds of fishing line. Fishing line requires a high tensile strength for big fish and low for small fish. Monofilament is a single strand of line and can stretch. You might want to reword this sentence as it stands a little confusing possibly add fishing before line and replacing and with that.- Alysa Buck  Braided fishing line will not stretch but is very strong. Fluorocarbon line is not as strong as the others but still popular. Hypothesis If different types of fishing line are put under a tensile strength test, the braided fishing line will have the highest tensile strength. How is this experiment "World Changing" what exactly is the experiment going to improve.(Alex Wiegand)

Don't forget to add safety goggles and scissors to your materials list!

Those should be added to your methods list.- Alysa Buck Good work so far Mitch, this is a really creative and purposeful experiment. I was wondering how you are going to have quantitative data in this experiment? You mentioned in the background information that tensile strength is measured in newtons... How are you going to orient newtons into this... does the spring scale act solely as a weight or does it give off a newton measurement as well? (Bri Mosher)
 * 1) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">First, start by making sure your spring scale is secured in some way so that the line can be pulled down. Possibly attach crossbar to ring stands and hang the spring scale on that.
 * 2) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">Cut each type of fishing line into 1 foot(30.48 cm), 3 strings per type ....... Periods.....
 * 3) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">Put on safety goggles.
 * 4) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">Tie the first length of monofilament fishing line to the end of the spring scale ....... Periods.....
 * 5) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">Pull on the line until it breaks. Record when it broke and any notable characteristics of the string. How are you going to pull the string just with your hand? if so you may need to determine how fast/slow you pull. This may effect your data.(Alex Wiegand) Will it break from just pulling or should you incorporate something like weights? Ms. Miller
 * 6) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">Repeat step 5 with the second length of monofilament fishing line ....... Periods.....

 * 8) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">Repeat steps 4 through 7 with the other sets of fishing line ......... Periods.....
