1.
It is used to draw arcs and circles in pencil or ink.
Correct Answer
B. Compass
Explanation
A compass is a tool that is specifically designed for drawing arcs and circles. It has two arms, one with a pointed end and the other with a pencil or ink attachment. By adjusting the distance between the arms, the user can create circles of various sizes. This makes a compass the ideal tool for accurately drawing curves and circles in pencil or ink.
2.
It is used as a guide in drawing in horizontal lines and serves as a support for the triangles when drawing vertical and inclined lines.
Correct Answer
C. T-square
Explanation
A t-square is a tool used in drafting and drawing to create straight horizontal lines. It is also used as a support for triangles when drawing vertical and inclined lines. The t-square has a long straight edge that is perpendicular to the shorter crossbar, allowing for accurate and precise measurements. It is an essential tool for maintaining straight lines and angles in technical drawings and designs.
3.
It is usually used in order to project some irregular shape of curve in a particular drawing.
Correct Answer
A. French curve
Explanation
A French curve is a drafting tool that is commonly used to project irregular shapes or curves onto a drawing. It is designed with a variety of curved edges, allowing it to be maneuvered to match the desired curve. By aligning the French curve with the curve that needs to be projected, the user can trace the shape onto the drawing surface. This tool is particularly useful when drawing freehand curves or when replicating complex shapes that cannot be easily measured or drawn with a straightedge.
4.
This instruments is used to erase unwanted marks on the drawing paper.
Correct Answer
B. Eraser
Explanation
An eraser is used to erase unwanted marks on the drawing paper. It is a tool made of a soft material, such as rubber or vinyl, that can be rubbed against the paper to remove pencil or graphite marks. Erasers are commonly used by artists, students, and anyone who needs to correct or modify their drawings or written work. They are designed to be gentle on the paper while effectively removing the marks without leaving any residue.
5.
This instrument has a calibrated angel or degree ranging from 0 to 360 degree. It is primarily use to plot on the drawing.
Correct Answer
C. Protractor
Explanation
A protractor is a measuring instrument that has a calibrated angle or degree ranging from 0 to 360 degrees. It is primarily used to plot angles or measurements on a drawing. A triangle is a shape with three sides, a ruler is a straight edge measuring tool, and a rectangle is a four-sided shape with opposite sides that are equal in length. None of these options match the description of an instrument used for measuring and plotting angles like a protractor does.
6.
What drafting tool is this?
Correct Answer
A. Plastic slope
Explanation
The given answer "Plastic slope" is the correct answer as it accurately describes the drafting tool shown in the question. The term "plastic slope" refers to a drafting tool made of plastic material that is used for creating inclined or sloping lines.
7.
What drafting tool is this?
Correct Answer
A. Compass
Explanation
This drafting tool is a compass. A compass is a tool used for drawing circles and arcs. It consists of two arms, one with a pointed end and the other with a pencil or pen attached. The pointed end is used as a pivot point, while the pencil or pen creates the desired shape.
8.
What drafting tool is this?
Correct Answer
A. Ruler
Explanation
The correct answer is "Ruler" because it is a drafting tool commonly used to draw straight lines and measure distances accurately. It typically has markings in inches or centimeters along its length, allowing for precise measurements. A ruler is an essential tool in various fields such as architecture, engineering, and graphic design, where accuracy and precision are crucial in creating detailed drawings and designs.
9.
Which type of pencil is used when extreme accuracy is required?
Correct Answer
D. Hard Pencils
Explanation
Hard pencils are used when extreme accuracy is required because they have a higher graphite content and produce a lighter and more precise line. The harder graphite allows for better control and the ability to create fine details. Soft pencils, on the other hand, have a higher clay content and produce a darker and less precise line, making them more suitable for shading and creating broader strokes. Medium pencils fall in between hard and soft, offering a balance between precision and darkness. Therefore, hard pencils are the best choice when extreme accuracy is needed.
10.
What type of pencil is used for general purpose in drawing?
Correct Answer
A. GrapHite pencils
Explanation
Graphite pencils are the correct answer because they are commonly used for general purpose drawing. Graphite is a versatile material that allows for different shades and levels of darkness, making it suitable for various drawing techniques. Medium pencils and Mongol pencils may also be used for drawing, but they are not as commonly associated with general purpose drawing as graphite pencils. "Instrument pencil" is a vague term and does not specifically indicate a type of pencil used for drawing.
