Understanding Object Views and Projection Systems in Technical Drawing
Understanding the Views of an Object
The main view of an object is obtained through orthogonal projections onto six planes arranged in a cube. We can define views as the orthogonal projections of an object according to the different directions from which it is observed.
Title of the Views
If we place an observer according to the six directions indicated by the arrows, we obtain six possible views of an object:
- View A: Front view or elevation
- View B: Top view or plan
- View C: Right side view or right lateral
Electromagnetic Induction: Analyzing a Sliding Wire in a Magnetic Field
Analyzing a Sliding Wire in a Magnetic Field
A wire of length L is sliding with velocity vx > 0 without friction on rails that form part of a circuit with resistance R. A uniform magnetic field of magnitude B points into the paper.
[a] Find the induced emf E and the current I in the circuit, indicating the true positive direction of the current that flows in the sliding wire (up or down on the paper).
[b] Find the magnitude and direction of the magnetic force on the sliding wire in terms of B, L,

Color Theory: Ranges, Properties, and Applications
Color Ranges
Establish colors that have a relationship with each other, that are close on the chromatic circle.
- Warm Range: Involves magenta, yellow, red, orange, ochres, and earth tones. These colors evoke feelings of closeness and force.
- Cold Range: Involves blue, violet, and green. These colors evoke feelings of distance, cold, calm, tranquility, and spirituality.
- Monochromatic Range: Formed by a single tone, including a scale of that color. For example,
Understanding Polygons, Quadrilaterals, and Polyhedrons
Understanding Polygons
A polygon is a part of a plane delimited by a closed polygonal path (it is called a polygonal region). It can be:
- Convex: Prolongation of all segments of the polygonal path divides the plane into two semi-planes, and the polygonal path is all in the same semi-plane.
- Concave: Prolongation of at least one segment of the polygonal path divides the plane into two parts, each one in different semi-planes.
- Regular: When all the sides and angles are equal.
