The End Essay Example

circular direction. There is an inverse relationship between torque and speed in gearing. A ten-speed bicycle has ten different gear selections. When you pedal up a hill, you use a gear train that provides more torque (turning force) UT, in doing so, less speed.

1. When you pedal on flat land, you use a gear train that provides more speed, but in doing so, less torque within the gear train. When peddling up a hill, we trade off speed for torque. In other words a reduction in speed is a trade-off to increase torque and make peddling easier. The drive gear is the input gear; the driven gear is the output gear. Label the drive and driven gears in the two diagrams below. The gear train in which diagram provides more torque? < (Less) The gear train in which diagram provides more speed? (More) Which gear train would you use to ride up a hill? (Less Speed)
2. Fill in the chart below to show the relationship between torque and speed in gear trains. More Torque When you travel up hill, more than likely you would travel at a low rate of speed. More Speed When you are traveling on flat land then you tend to go quite faster Gear Size As the size of the driven gear decreases in relation to the size of the drive gear, output speed increases. As the size of the driven gear increases in relation to the size of the drive gear, output torque increases.
3. Complete the chart below. Show the relationship between drive gear and driven gear in a simple gear train. Driven Gear Size To Increase Torque The gear
   

size would be at the Max. To Increase Speed The gear size would be at the lowest

Big Wheel

I think it would be the same as the Small Wheel, I think this because they look they are the same but one is bigger than another. Gears I think the gears would stay the same speed because usually gears go the same speed. Also the force would be the same because Gears are pretty Strong. Man Pulling String The man pulling the string would have the same speed until he got tired the he would need to apply more

and more speed. He would be in the same direction because all he is doing is pulling string that is connected to a huge wheel, so you would have to pull in the same direction.

Woman pulling the Bell The woman would have different speed every time she pulls the string to the bell, because it depends on if she's late on pulling the bell and she has to pull as fast as she can. The woman taping the thing As I said like she was pulling the bell her speed would be at different rates because she is applying more force or less force each time.

Conclusion

Label the input and output for each of the pictures shown below. Then write the type of movement for each. Input- Output- This input would a Rotary. This would be a Rotary also. This would be Oscillating. This would be a Rotary.
