Grade 8
Hydraulics
Syringes can be used to change the type & size of an input movement into a different output movement
ACTIVITY 1
Set up the investigation illustrated by the drawing above:
- Use two 10-ml syringes with approximately 200 mm length of plastic tubing.
- Use water in the system.
- Use syringes A as the master cylinder.
1. Observe and write down what happens at syringe B:
- .......................................................................
2. Compare the distances
- .......................................................................
- .......................................................................
ACTIVITY 2
Repeat the investigation using a 60-ml syringe as the master and a 10-ml syringe as the slave.
2. Observe and note what happens.
- .......................................................................
- .......................................................................
3. Choose the correct options. If the plunger of the master syringe is pushed down 10 mm, the plunger of the slave will have moved:
A. 10 mm B. less than 10 mm C. more than 10 mm
Complete the system diagram below:
1. How is the input size changed?
- .......................................................................
2. How is the input type changed?
- .......................................................................
3. How would you describe the mechanical advantage that we get from a hydraulic system?
- .......................................................................
