Sure, let's go through each question step-by-step to determine the correct answers.
### Question 1.1
In Technology drawing, Scale 1:2 means that the drawing is drawn at:
- A. the actual size of the model
- B. two times the size of the model
- C. half the size of the model
- D. twelve times the size of the model
Explanation:
In technical drawing, a scale represents how the dimensions on the drawing relate to the actual dimensions of the object. The ratio 1:2 means that one unit on the drawing is equal to two units in reality. Therefore, the drawing is half the size of the actual model.
Correct Answer:
- C. half the size of the model
### Question 1.2
The design brief clearly indicates:
- A. what the designer is going to make to solve the problem.
- B. what the designer is going to ask about to solve the problem.
- C. what the designer does not want to do.
- D. what steps will be followed in problem solving.
Explanation:
A design brief is a document that clearly outlines the objectives and scope of a design project. It defines what the designer needs to create or develop to address a specific problem or fulfill certain requirements.
Correct Answer:
- A. what the designer is going to make to solve the problem.
### Question 1.3
According to Pascal's principle, the pressure exerted on one part of the hydraulic system is transferred...
- A. equally to all parts of the system
- B. without any losses
- C. in all directions to other parts of the system.
- D. all of the above
Explanation:
Pascal's principle states that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container. This means that the pressure is distributed equally in all directions.
Correct Answer:
- A. equally to all parts of the system
Summary of Correct Answers:
1.1 - C. half the size of the model
1.2 - A. what the designer is going to make to solve the problem
1.3 - A. equally to all parts of the system
