Make a force meter – inquiry activity A spring can be used to make a force meter Apperatus • Stand and 2 clamps • Metre rule • Spring • Mass holder and masses • G clamp • Objects to weigh Before a spring can be used to make a force meter it needs to be calibrated. Force meters measure the weights of different masses. I … When you hold the force meter upright, the band will hang down. It needs to be calibrated.Stick a piece of tape along the visible part of the narrower tube. There are different forces throughout the world and the universe that can act upon objects to create motion or movement. Activity - complete the attached Stretching springs worksheet. on Introduction. 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. on Introduction. Assess where it falls on the poster board and mark this as "1 N" for 1 Newton. The meter does not show acceleration or deceleration; instead it is strictly lateral. Forcemeter Experiment. Slight modifications could make the forcemeter quite accurate: Use of vernier calipers with spring materials used in highly linear ranges ect. Acceleration is the change in velocity, which is speed in a given direction, per unit of time. Torque can be defined asthe tendency of a force to rotate an object about an axis and is estimated by multiplying the distance (the distance from the pivot point to the area where force is applied) and that force applied. 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. (Simple Static/dymanic friction is quite interesting, fun to experiment with!). Add a known weight. This gave me the idea: the known mass (i.e. 13 years ago A fun one is to fire toy cars across the floor; how far will it travel when fired with a force of X Newtons? That way a simple pressure gauge can be used to indicate the force in pounds. They also snap occasionally, especially if stretched to their limits. Force meters measure the weights of different masses. You can make a force meter with a few household objects. Recalibration would be needed every time the bands are replaced. Label this "0 N" to represent 0 Newtons. There are two kinds of force gauges today: mechanical and digital force gauges. Making a force meter Forces and Their Effects Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

The pedal force meter series 1.0 for two-wheelers is used for measurement of the forces on the handbrake lever of motor cycles. Learners apply their measuring skills by suggesting different forces that can be measured using a force meter before predicting and then measuring the forces. SF-500 Force Gauge Digital Force Gauge Push and Pull Tester, 500N 100-240V Digital Force Gauge Push and Pull Tester Meter Dynamometer, Digital Force Gauge (US Plug) 5.0 out of 5 stars 1. A 50g mark should be labelled 0.5N etc.Either by eye or my measuring and marking, you should now be able to complete the scale on your force meter, filling in gaps and extending the scale to the end of the narrower tube.The exact range of your meter will depend on the thickness, length and age of your band, and on the length of your tubes. Once you have completed the sheet and had it checked then you should try to carry out the same experiment. ), Participated in the The Instructables Book Contest. This activity is useful in classroom and home school environments. $138.48 $ 138. So force meter is a fancy term for a scale here? Mechanical force gauges. Gareth Branwyn is a freelance writer and the former Editorial Director of Maker Media. Acceleration is expressed as centimeters per second per second, which is centimeters per second squared. 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). Smooth the cut edges with sandpaper, your rotary tool, or by scraping with a knife.Drill or melt holes in the tubes. An object’s mass is the amount of matter that it contains and is expressed in grams or kilograms. 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. Pictures are good, congrats for your effort. It's a lot easier for you if the weight is … 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. To measure force, look at the formula force equals mass times acceleration (F=M*A). This means you find out how much. Cut a second piece of cardboard into a 2-cm by 2-cm square and set aside. Lay the rectangle on a flat surface and use tacks or a stapler to attach the elastic band to one side. You could make a big meter, out of timber and bungees, and measure the force needed to push your car on different road surfaces. 13 years ago Applications exist in research and development, laboratory, quality, production and field environment. Develop a deeper understanding of forces, mass, weight, gravitation, vectors, and more with an easy to make force meter. Holy Redeemer: Building Your Own Force Meter, Hyper Text Book: Things That Weigh a Newton. Question This neat little device can be built for almost nothing (I used plumbing off-cuts), but will let you measure pushes and pulls around you, as well as doing experiments with different-sized forces.It is perfect for kids still at school as well; it can be made by dads-and-lads together, or by competent older children alone, and it can be calibrated in Newtons and used to do home experiments to reinforce schoolwork (any UK readers with kids in Years 6 or 9, this will help them get ready for their SATs). A spring meter is one kind of force meter, and the most common used for teaching purposes. The spring scale is measured in Newtons. 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. I like this meter! It's a lot easier for you if the weight is sensible number (say 100g, 200g, 50g), as you will be using it to draw your scale. Do not place any masses on the meter. 1 year ago Add an object that weighs 1 Newton to the force meter. Stick a piece of tape along the visible part of the narrower tube. The pedal force meter series 2.x for cars and HGVs measures forces acting on the foot pedal or the parking brake. It needs to be calibrated. 12 years ago 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. 9 years ago Your meter is essentially finished, but you cannot yet actually measure any forces with it. 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. http://en.wikipedia.org/wiki/Spring_scale to measure both pulling and pushing force. The weight is the pull on the mass due to the local gravity-field (i.e. Assess where it falls on the poster board and mark this as "1 N" for 1 Newton. Making a force meter. (I may still add a drop of glue to the knot, just to be sure.). Smile indeed! Students weigh each object and record the weight in Newtons, e.g. A mass of 100g actually weighs a smidge under one Newton (1N). Cut the tubes to convenient hand-held lengths, say 20cm for the narrower tube and 4 or 5cm for the wider. How can a spring be used to measure a force? Use this for a chart to measure Newtons. (Perhaps you would like to add a comment with ideas for other uses for this instructable? Make a mark on the tape where the bottom edge of the wider tube is. Hang your force meter on a clamp stand and with no masses attached, mark the bottom of the spring with a fine line round the tube and label it with the value 0 N. (N = Newton) Hang a 100 g mass on the force meter, calculate the weight of the mass here on Earth and where the bottom of the spring is now, draw a line round the tube and label it with its weight in Newton’s 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).
