Can someone let me know if I did this lab correctly. It's about levers
Lever Lab Name: _Shyla Layla 1st Class Lever A 1) Attach a mass 25cm from the fulcrum. This will act as the load. Attach a spring scale 25cm from the other end of the fulcrum. Measure how much effort force is needed to lift the load. 5 the fulcrum. Move the spring scale 5 cm from the fulcrum. Record the effort )Leave the load 25 cm from the fulcrum. Move 3) Leave the load 25 cm from the fulcrum. Move the spring scale 45 cm from the fulcrum. Record the effort force needed to lift the load. 2. 5 N ) Return the spring scale to its original location in STEP 1, 25 cm from the fulcrum. Move the load 5 cm from fulcrum. Record the effort force needed to lift the load. 0. 8 N )Leave the spring scale 25cm from the fulcrum. Move the load 45 cm from the fulcrum. Record the effort force needed to lift the load. 5& N Questions ) Using the results from #1,2 & 3, make a general statement about how the distance the effort force is from the fulcrum effects the effort force needed to lift the load. when the effort is farther from the fulcrum, there is less effort headed to lift the load . 2) Using the results from #1,4 8 5, make a general statement about how the distance the load force is from the fulcrum effects the effort force needed to lift the load. When the load is closer to the fulcrum, less effort is needed to lift it ) Put all the results together. How should a First Class Lever be set up to minimize the effort force needed to lift a load? (In other words, where should the effort force, load force and fulcrum be positioned?) Experimentally confirm your set up. I would move the load closer to the fulcrum and move the effort farthest as possible from the fulcrum . The fulcrum would be in the middle of the effort and load . Give an example of a real world First Class Lever. Explain how the explanation to question #3 will make the job easier for your chosen lever. A Seesaw would be an example of a first-class lever . If we made a seesaw look like this ; then - it would make it easier for timmy to tways be on the " down side " . While it is also easier for bobby to be on the up side ! " 2nd Class Lever A 1) Set up your lever as shown. Leave the load in place and move the effort force. When is it easiest to lift the load? when the effortis farther from the object ) Leave the effort in one place. Move the load? When is it easiest to lift the load? in the load is farther from the effort , Co it is easier to lift 3) In the wheelbarrow b ere should the load be placed to make it easier to lift? Farther to the front of the wheelbarrow 4) How could the wheelbarr be modified to make it easier to lift the load? Longer handles 3rd Class Lever A ) Set up your lever as shown. Leave the load in place and move the effort force. When is it easiest to lift the load? When the fforce Is closer to the load, then less effort is needed to move it. 2) Leave the effort in one place, Move the load? When is it easiest to lift the load? It's easier when the load is farther from the effort O A shovel is an example of a 3rd Class Lever. In theory, how would one use a shovel to make lifting a load as easy as possible. A sketch would be helpful. The theory may be impractical to actually do. you would hold the shovel by the h a the handle closest to the fulcrum as possibly And position the Food farthest from the effort as possible X CamScanner
