Mechanical Advantage of Inclined Planes and Pulleys. Increase the number of ropes supporting the load. Most students should skip to the final two or three minutes which explain the basics of calculating IMA of a lever from different ratios. 10 are used to lift cars and even houses. Watch children in 4th grade and 5th grade flit between the simplicity and complexity of machines. Interested students may want to work their way through it. Once again we have to exert force over a longer distance to multiply force. Combining this with the information in the paragraphs above, we can write. State the equation for efficiency of a simple machine, and calculate Wo and Wi. Work and machines worksheet pdf form. Cars and other vehicles are combinations of many machines. In addition, the High School Physics Laboratory Manual addresses content in this section in the lab titled: Work and Energy, as well as the following standards: - (D) demonstrate and apply the laws of conservation of energy and conservation of momentum in one dimension. The first part of this video shows how to calculate the IMA of pulley systems.
The student is expected to: - (C) describe simple and complex machines and solve problems involving simple machines; - (D) define input work, output work, mechanical advantage, and efficiency of machines. The reason why this cut and glue pdf for grade 4 and grade 5 is a sure scene-stealer is it defines each simple machine as simply as could be. If the rod has a diameter of 1 cm and the IMA of the machine is 6, what is the radius of the handle? Work and machines worksheet pdf worksheets. Because the amount of work is not changed, the term f d does not change, but force can decrease if distance increases. Beautifully baked into our free, printable simple machines worksheets is the fact that in life we are increasingly at the mercy of machines, simple or complex, and therefore we must equip ourselves to identify each machine that we encounter every day as a lever, pulley, inclined plane, wedge, wheel and axle, or screw. The circular handle of a faucet is attached to a rod that opens and closes a valve when the handle is turned. Force applied to the outside of the wheel causes a greater force to be applied to the rope that is wrapped around the axle.
BL] [OL] The calculation for IMA of a pulley seems too easy to be true, but it is. BL] [OL] Be sure students understand that a complex machine is just a combination of simple machines and is still fairly simple. 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. Work and machines worksheet pdf 2020. Let's examine how this works in practice. Explain why more energy is usually lost to friction with these machines than with other simple machines. Lever||mechanical advantage||output work||pulley||screw|.
Efficiency of a Lever. The axle on a vehicle does not do work on a load. The beginning of this video may cause more confusion than illumination. 12 shows three different pulley systems. The student knows that changes occur within a physical system and applies the laws of conservation of energy and momentum.
Sort the machines into one of the 6 types. Have the students compare this screw to a wood screw and a circular stairway. AL]Tell students there are two other classes of levers with different arrangements of load, fulcrum, and effort. The overhang you may have seen on the end of old barn roofs is where a pulley was once attached. 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. BL] [OL] Ask the students what they know about machines and work. Show them that it looks more like a lever if the wheel is replaced by a crank.
Remind the students that, for an ideal machine, work in = work out and that W = f d. The video shows how to find the fs and the ds. A complex machine is a combination of two or more simple machines. 13 combine two levers and two wedges. When you go down a slide at a park, the simple machine whose industry you owe a debt of gratitude to is an inclined plane. Simple machines make work easier, but they do not decrease the amount of work you have to do. In general, the IMA = the resistance force, F r, divided by the effort force, F e. IMA also equals the distance over which the effort is applied, de, divided by the distance the load travels, dr. Getting back to conservation of energy, for any simple machine, the work put into the machine, Wi, equals the work the machine puts out, Wo. For a pulley system, the input distance is how far you pull the rope, and the output distance is the distance the load rises. Examples of this type of lever are baseball bats, hammers, and golf clubs. In another type of lever, the fulcrum is at the end of the lever and the load is in the middle, as in the design of a wheelbarrow. Use the Check Your Understanding questions to assess students' achievement of the section's learning objectives. Efficiency in real machines will always be less than 100 percent because of work that is converted to unavailable heat by friction and air resistance. Identify each object and write which simple machine it is.
Both children sit at equal distance from the fulcrum. 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. Our worksheets on the simple machines are ideal for grade 3, grade 4, and grade 5. Calculating Mechanical Advantage and Efficiency of Simple Machines. The heavier child sits farther from the fulcrum. Simple machines are the building blocks for creating more complex machines. Why can't simple machines change the amount of work that you do? So, why is a simple machine useful? There are six simple machines: lever, inclined plane, wedge, pulley, wheel and axle, and screw. Devices like the one shown in Figure 9. Don't let them confuse the term with complicated machines such as computers. AL] Ask students how the forces exerted by a wood screw are different from those exerted by the screw in Figure 9.
How could you use a pulley system to lift a light load to great height? In real life, some of the applied work always ends up as wasted heat due to friction between moving parts. Bicycles include wheel and axles, levers, screws, and pulleys. Although it cannot change the amount of work you do, a simple machine can change the amount of force you must apply to an object, and the distance over which you apply the force. Note that, when using an inclined plane the load moves, but when using a wedge the load is stationary and the machine moves. Increase the number of pulleys. Explain how heat lost because of friction assures that Wo will always be less than Wi preventing efficiency from ever reaching 100%. How would lubrication affect the efficiency of a simple machine? For instance, a bicycle is created using wheels, levers, and pulleys.
For an additional fun activity, have the students search the Internet for Rube Goldberg machine. 10 shows the simple formulas for calculating the IMAs of these machines. Explain that the combined mechanical advantage can be great. This video shows how to calculate the IMA of a lever by three different methods: (1) from effort force and resistance force; (2) from the lengths of the lever arms, and; (3) from the distance over which the force is applied and the distance the load moves. 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. All sloping, paved surfaces for walking or driving are inclined planes. Any crank-operated device is an example of a wheel and axle.
BL] [OL] See if the students grasp the idea that a wheel and axle is really a type of lever.
