Gears Practice Test. Key 1. If gears are connected by a chain or belt, they move in the direction. * Opposite Same 2. If gears are meshed (touching), then adjacent gears move the directions. * Opposite Same 3. In the photo, which direction are the gears moving? * Opposite Same 1 /8 4. When more than two gears are together, you should the middle gears when determining direction. * Count Measure Ignore Add 5. In this diagram, what direction does gear 6 rotate compared to gear 1? * Clockwise Counterclockwise 2 /8 6. The diagram shows an object that is moving . * Clockwise Counterclockwise 7. The diagram shows an object that is moving . * Clockwise Counterclockwise 8. When more than two gears are together, the smaller gear will always rotate than the larger gear. * Faster Slower 3 /8 9. Meshed gears with an equal number of teeth will turn at the speed. * Opposite Same 10. To determine how fast a gear is turning in relation to another, you should . * Observe the direction Measure the size Count the teeth 11. What is the speed of gear 3 if gear 1 rotates at 15 rpms? * 5 rpms 3 rpms 10 rpms 6 rpms 12. Gear three will rotate than the other gears. * Slower Faster 4 /8 13. If gear A turns one revolution, how many times will gear B turn? * 2 .5 1 1.5 14. In the diagram, which gear revolves the fastest? * Gear A Gear B 15. In the diagram, what is the ratio for gear A? * 1.75 2 .75 .57 5 /8 16. In the diagram, what is the ratio for gear B? * 1.75 2 .75 .57 17. If gear B is rotating at 400 rpm, how fast is gear A spinning? * 728 500 650 228 18. Wheel A is rotating at 300 rpms in a counterclockwise direction. What is the speed and direction of wheel C? * 500 375 175 200 6 /8 19. If gear A is rotating clockwise, which direction is gear B rotating? * Clockwise Counterclockwise 20. What is the ratio of gear 4? * 1:2 1:1 2:1 2:2 7 /8 .
