The student knows that changes occur within a physical system and applies the laws of conservation of energy and momentum. While we push staples through pieces of paper in order to fasten them together nearly every day, little do we realize we are making a simple machine, a lever to be specific, work hard.
Wo and Wi can always be calculated as a force multiplied by a distance, although these quantities are not always as obvious as they are in the case of a lever.

Work and machines worksheet pdf version. 13 combine two levers and two wedges.
Efficiency is related to friction, and friction depends on the smoothness of surfaces and on the area of the surfaces in contact. Refer back to the discussions of each simple machine for the specific equations for the IMA for each type of machine. BL] [OL] Ask the students what they know about machines and work. AL]Tell students there are two other classes of levers with different arrangements of load, fulcrum, and effort. Pulleys were once seen on sailing ships and farms, where they were used lift heavy loads. Teaching tip—When calculating efficiency, it is easy enough to understand what force in and force out are: the force you apply is force in and the weight of the object that is being lifted is force out. Interested students may want to work their way through it. The other three are not as obvious. When you prod the cake with your fork, the simple machine in action is a wedge. This printable simple machines worksheet, where the task is for the grade 3 children to match each simple machine to an example by drawing a line, will get the quiet machine enthusiasts splendidly eloquent. Both the input work (Wi) and output work (Wo) are the result of a force, F, acting over a distance, d. Work and machines worksheet pdf.fr. The efficiency output of a machine is simply the output work divided by the input work, and is usually multiplied by 100 so that it is expressed as a percent. By the end of this section, you will be able to do the following: - Describe simple and complex machines.

Both work values are the product Fd. Explain why more energy is usually lost to friction with these machines than with other simple machines. Of all simple machines, mechanical advantage is easiest to calculate for pulleys. BL] [OL] Talk about how inclined planes and wedges are similar and different. So, why is a simple machine useful? For instance, a bicycle is created using wheels, levers, and pulleys. Increase the number of ropes supporting the load. The overhang you may have seen on the end of old barn roofs is where a pulley was once attached.
8(a), the worker uses a type of lever to exert a small force over a large distance, while the pry bar pulls up on the nail with a large force over a small distance. This results in a smaller force acting over a greater distance at the end of the resistance arm. Recall that in closed systems the total amount of energy is conserved. Bicycles include wheel and axles, levers, screws, and pulleys.
Not only does this simple machines worksheet work well as an instant pick-me-up for the thriving scientists in 3rd grade and 4th grade, it charmingly illustrates the characteristics of each simple machine type. Let's examine how this works in practice. Both children sit at equal distance from the fulcrum. Introduction to Mechanical Advantage. Force applied to the outside of the wheel causes a greater force to be applied to the rope that is wrapped around the axle. The effort force, applied at Fe, lifts the load (the resistance force) which is pushing down at F r. The triangular pivot is called the fulcrum; the part of the lever between the fulcrum and F e is the effort arm, Le; and the part to the left is the resistance arm, Lr. No simple or complex machines have the actual mechanical advantages calculated by the IMA equations. Combining this with the information in the paragraphs above, we can write. Sort the machines into one of the 6 types.
Work And Machines Worksheet Pdf.Fr
10 shows the simple formulas for calculating the IMAs of these machines. Why can't simple machines change the amount of work that you do? The down side is that you must exert the force over a greater distance, because the product of force and distance, f d, (which equals work) does not change. Most students should skip to the final two or three minutes which explain the basics of calculating IMA of a lever from different ratios. True or false—The efficiency of a simple machine is always less than 100 percent because some small fraction of the input work is always converted to heat energy due to friction. Note that, when using an inclined plane the load moves, but when using a wedge the load is stationary and the machine moves. Be sure students do not equate machines and motors by asking for (and, if necessary, providing) examples of machines that are not motorized. Give some examples: hand-powered windlass, steering wheel, door knob, and so on. The beginning of this video may cause more confusion than illumination. Dispel any misconceptions that machines reduce the amount of work. Check Your Understanding. Energy loss to friction is reduced, but nothing is lifted. Simple Machines Worksheets. Note that the IMAs of the individual simple machines in a complex machine usually multiply because the output force of one machine becomes the input force of the other machine.
NGSS: 3-5-ETS1-1, 3-5-ETS1-2, 3-5-ETS1-3, 3-PS2-1, 3-PS2-2. To raise a load 1 meter with a pulley system you have to pull N meters of rope. The ideal mechanical advantage, IMA, is the mechanical advantage of a perfect machine with no loss of useful work caused by friction between moving parts. The first part of this video shows how to calculate the IMA of pulley systems. How could you use a pulley system to lift a light load to great height? There are six simple machines: lever, inclined plane, wedge, pulley, wheel and axle, and screw. 4 m, which lifts a 40 N weight resting on the resistance arm a distance of 0. Complex machine||efficiency output||ideal mechanical advantage||inclined plane||input work|. The car, with its engine and four wheels has to be a complex machine. Since both have different weights, they will never be in balance. Ask them why steering wheels had a greater diameter before power steering was invented. Lever||mechanical advantage||output work||pulley||screw|. The circular handle of a faucet is attached to a rod that opens and closes a valve when the handle is turned. Wood screws (of course) are also examples of screws.
Explain that simple machines are often hand-held, and that they reduce force, not work. Review what was learned about the IMA of inclined planes and pulley systems before watching the video. In real life, some of the applied work always ends up as wasted heat due to friction between moving parts. Increase the number of pulleys. In the formula for IMA, the distance between screw threads is called pitch and has the symbol P. [BL] [OL] Suggest that a screw is classified as a separate type of simple machine perhaps because it looks so different from what it really is—an inclined plane which sometimes is turned by a lever.
