2.1 Underline the correct word in the brackets.

Here are the answers to Activity 2:

2.1 Underline the correct word in the brackets.
Pascal's principle: when pressure is applied to a fluid, the force is transmitted (equally / unequally) in all directions.
The correct word is equally.

2.2 Fill in.
Newton is the unit in which force is measured in a hydraulic system.

2.2.1 With two equal syringes, we get equal distance and equal force between the two syringes.
This statement is correct.

2.2.2 In a hydraulic system where movement is from a small syringe to a larger syringe, the output distance is smaller and the output force is larger.

2.2.3 When the output force is increased by the force transfer from the input force, we call this mechanical advantage.

2.3 Study the hydraulic system below and answer the questions that follow.

2.3.1 Use the picture above to explain how forces within a hydraulic system are transferred.
