This project will show you how to take a couple commonly available devices, and create a homemade force gauge, for about half the price of what you can buy one for. An everyday scale for measuring weight is a kind of force meter, but the term usually refers to the kind of device that takes advantages of Hooke's law for elastic materials, such as springs. Your meter is essentially finished, but you cannot yet actually measure any forces with it. (I may still add a drop of glue to the knot, just to be sure.). Continue measuring and marking for 2 through 5 Newtons. F = Force (often measured in Newton). That is why the scale is drawn on tape - you can easily change or replace it when the band needs replacing. The wire I used was quite smooth, so required three over-hand knots in opposite directions to lock. This activity is useful in classroom and home school environments. FREE Shipping by Amazon . Turn the meter round, and (still holding the outer tube) you can use the inner tube to measure the force of a push, or to weigh something that won't hang on the loop, such as balls or eggs.You can also use the meter to investigate the effects of known forces, pushing or pulling until the meter reads a certain force and observing the effects. (*Note*: cut the piece of on Introduction. I like this meter! I'm adding a loop: Thread the wire through the two unused holes in the inner tube and tie a knot to hold it in a loop. on Introduction. It was a prize in the first Valentine contest I entered.Some online suppliers do free engraving, if you want one with your name on. I did only design the meter to be a short-life project anyway, to help Year Six kids (age 11) do extra work to support their SATs (UK version). It introduces force as a simple concept of push and pull; lets pupils explore the movements of objects when force is applied; invites pupils to measure the force of carrying an object using a force/Newton meter. Students weigh each object and record the weight in Newtons, e.g. Hold your meter upright, standing by the poster board to calibrate it. Add an object that weighs 1 Newton to the force meter. Will build one (with a tensile property testing rig, see below) and post during December holiday! You can use anything you want - hang a pound weight on there, draw a mark and call it pounds. Rubber bands age and perish, and they stiffen as they do, so you will need to check the calibration of your meter every few weeks. Should get the creative juices flowing for kids needing a project for school. That way a simple pressure gauge can be used to indicate the force in pounds. Do not place any masses on the meter. Plus it's fun to make some of our own tools. pub, 158 KB. Acceleration is expressed as centimeters per second per second, which is centimeters per second squared. Secondly, just to make sure: F = m * a -> Force (caused by the weight of an object) = mass (grams/pounds meassured value ect.) Stating the obvious rubber bands deteriorate somewhat rapidly. A force meter, also called a newton meter, is used to measure forces Forces can be contact forces, where objects must touch each other to exert a force. http://en.wikipedia.org/wiki/Spring_scale. (Perhaps you would like to add a comment with ideas for other uses for this instructable? Either hang it off the hook or balance it on the narrower tube. Pictures are good, congrats for your effort. Form the paper clip into a "hook" shape on one end. If a mark was due to a 100g mass, label it 1N. Put the narrow tube inside the wide tube, with the holes at the same end, and the outer holes lined up with two of the inner holes. acceleration ({constant, g} gravity = 9.81m/s^2) Thus, 100g mass is pulled toward the earth by gravity with a force = 0.981N Finally, your design could used to measure the max static force required to move an object and overcome the force it's friction with a certain surface can support, from which static friction constants can be derived. Force meters measure the weights of different masses. This editable Science PowerPoint lesson can be used as an introduction to studying the topic of Forces.

Cut a second piece of cardboard into a 2-cm by 2-cm square and set aside. You need two in the wider tube, both near one end, opposite each other, and four in the narrower tube, all at the same end, spaced every 90 degrees around the tube).Smooth the edges of the holes to stop friction wearing through the rubber bands (you will not need to do this if you melt the holes).Melting holes:Hold a nail in pliers, and heat it in a flame. Slight modifications could make the forcemeter quite accurate: Use of vernier calipers with spring materials used in highly linear ranges ect. Hold the meter by the outer tube.Objects can be hung from the loop or hook to find weights, or pulled with them to measure the force needed to move it (say, if you were investigating friction). A force meter, also known as a Newton meter, can be measured in Newtons to determine the amount of force exerted on a particular object. Measure unknown masses and determine how many Newtons each object weighs. calibrate it. Use metal washers to stop the rubber band slipping back out of the holes. Label this "0 N" to represent 0 Newtons. A candle or lighter flame will do, but this is a case of "hotter is better", so I use a blowtorch or a bunsen burner. I guess you could replace the short lived rubber band with a couple of springs. Enjoy! I have been keeping an eye out for a hydraulic cylinder that has a bore area of exactly of 1 square inch. Idea Sheets are cross-referenced to subjects listed in the Common Core, Next Generation Science Standards, and California Content Standards. A mass of 100g actually weighs a smidge under one Newton (1N). The weight is the pull on the mass due to the local gravity-field (i.e. A mass of 1kg weighs 9.8N.Label the marks you made in multiples of 1N. A fun one is to fire toy cars across the floor; how far will it travel when fired with a force of X Newtons? 13 years ago It needs to be calibrated.Stick a piece of tape along the visible part of the narrower tube. You could even make up your own scale, based on any repeatable unit you want, but your results won't make as much sense to other people (although graphs etc would still be the same shape, so general conclusions could be reported). Reply Hang a large piece of poster board on the wall. Using a straightened-and-bent-in-half paper-clip as a "needle", thread the rubber band through the four holes in a line. Forcemeter Experiment.
