Inclined+Planes+in+Pyramids

1. With your partner, think of as many examples of inclined planes as you can. Record your list. Slide** Hills** Propeller** Grocery Ramps**
 * Handicap Ramp
 * Parking Ramp
 * Car Ramp
 * Escalator
 * Stairs**

2. Select a length for the inclined plane. Record the length, height, effort force and indicate whether or not it was successful. Repeat using various lengths.
 * Lab Instruction:**


 * Table 1: Inclined Plane**


 * **Inclined Plane Length (m)** || **Effort Force**
 * (newtons)** || **Success** ||
 * 4.74 || 311 || **/- Yes** ||
 * 2.26 || 652 || **X- No** ||
 * 4.76 || 310 || **/- Yes** ||
 * 3.62 || 408 || **/- Yes** ||
 * 3.00 || 491 || **X- No** ||
 * 2.54 || 582 || **X- No** ||
 * 4.00 || 369 || **/- Yes** ||

3. From your chart of data, find the maximum effort our crew member can sustain to pull the stone up the inclined plane.
 * What is the length of this inclined plane?**
 * [408n] 3.62m**

4. Would this be the ideal length to use for the inclined plane?
 * Yes, it would be an ideal length to use for inclined planes.**

5. What other factors might you consider? S**mooth Surface**

6. Defend your choice for the ideal length. __Give your reasons in complete sentences.__
 * I think smooth surface would be the best surface and its easier to push something or move something with smooth surface.**

7. Transfer the data for length and effort from Table 1 onto Table 2. - done-

8. Calculate the amount of work done to get the stone to the top of each inclined plane. **//Remember: Work = Force applied X distance mass is moved.//**


 * Table 2: Determining the Work done for the Inclined Plane**
 * Effort Force (N) X Distance (m) = Work Nm (J)**
 * **3,480 N** || **40 m** || **139,200 j** ||
 * 311 || 4.74 || **1.474.14** ||
 * 652 || 2.26 || **1,473.52** ||
 * 310 || 4.76 || **1,475.6** ||
 * 408 || 3.62 || **1,476.96** ||
 * 491 || 3.00 || **147,300** ||
 * 582 || 2.54 || **1,478.28** ||
 * 369 || 4.00 || **1,476** ||

9.How do the values of work found for the various lengths of inclined plane compare? __Use complete sentences in your answer. __
 * **The values of work found showed that all were equal to 1473 or 1478 and other numbers in between.** ||
