a straight line and a circle
False, other geometric objects exist which can be defined as a parrticular locus of points, such as the parabola and the hyperbola.
Drafting is done on a drafting table, with the help of a T-square, a compass, and other such devices.
Not sure. The answer is not "a set" since a set can also refer to collections of abstract concepts (not objects), they can be empty (collections of no objects), the elements of a set need not have anything in common.
The simplest lever can be constructed with a ruler and an eraser. Place the ruler on top of the eraser and you have a lever. Many other objects can perform the same function
An ellipsoid or a toroid or other 3-dimensional objects with more than one "holes". Or simply a ... sphere.
AutoCAD does not support parabolas. You would need to download an AutoLISP routine or approximate the parabola with it's geometric equation and a spline. The downside to an AutoLISP routine is that you do not know how good it is and it might not play nice with other commands.
You construct a Hexagon by drawing 8 lines that touch each other.
A "carpenter" is a skilled craftsperson who performed carpentry. Carpenters work with wood to construct, install and maintain buildings, funiture and other objects. -Wikipedia-
One can get second-hand drafting tables on Amazon and E-bay for cheap. Other websites which offer great quality drafting tables are Wayfair and Hayneedle.
A tensor is a mathematical object that generalizes the concepts of scalars, vectors, and matrices. It can represent relationships between geometric vectors, scalars, and other tensors. In physics and engineering, tensors are used to describe various physical properties and phenomena in a mathematical framework.
Allied drafting trades encompass various specialized fields that support the drafting and design process in construction and manufacturing. Key trades include architectural drafting, which focuses on building designs; structural drafting, which details the framework of structures; mechanical drafting, which involves the creation of mechanical components; and electrical drafting, which outlines electrical systems. Other trades may involve civil drafting for infrastructure projects and landscape drafting for outdoor spaces. Each trade requires specific skills and knowledge to accurately represent technical information and facilitate project execution.
Two common types of drafting machines are the parallel drafting machine and the adjustable drafting machine. The parallel drafting machine features a system of parallel bars that allow for precise movement of the drawing surface, ensuring accurate alignment and measurements. The adjustable drafting machine, on the other hand, allows for tilting and rotating the drawing surface to various angles, providing versatility for different drafting tasks. Both types enhance efficiency and precision in technical drawing and design.
