Sewing Machine Components Identification
The question asks to identify the parts of a sewing machine from the given options. Let's analyze each item:
- A. Flywheel: This is a part of a sewing machine, typically a large wheel that helps regulate speed and provides momentum.
- B. Agitator: This component is usually found in washing machines for stirring clothes, not in sewing machines.
- C. Presser foot: This part holds the fabric securely against the feed dogs and the throat plate while sewing.
- D. Feed dog: These are small metal teeth under the needle that move the fabric through the machine during sewing.
- E. Throat plate: Also known as the needle plate, this base plate has a hole for the needle and often markings to guide stitching.
Based on the analysis, the components that are parts of a sewing machine are the Flywheel (A), Presser foot (C), Feed dog (D), and Throat plate (E).
Therefore, the correct option includes A, C, D, and E.
Correct Answer Summary
The correct combination of sewing machine parts is A, C, D, E only.
