Mechanical Devices: Levers, Gears, Cams & Motion Systems
What Are Mechanical Mechanisms?
A mechanism is simply a device that takes an input motion and force and outputs a different motion and force. The purpose of a mechanism is to make a task easier to perform. The most commonly used mechanisms in mechanical systems include:
- Levers
- Linkages
- Cams
- Gears
- Pulleys
Understanding Levers
It’s important to understand how to calculate mechanical advantage obtained by using levers, the velocity ratio in levers and pulley systems, and the input and output speed when using

Basics of Diodes
- A diode is a two-terminal electronic component that allows current to flow in one direction only. It is formed by a p-n junction, where p-type and n-type semiconductors are joined together.
- When a forward bias is applied to the diode (positive terminal to p-type and negative terminal to n-type), the junction barrier is reduced, allowing current to flow.
- When a reverse bias is applied (positive terminal to n-type and negative terminal to p-type), the junction barrier is increased, preventing
Fundamental Electronic Circuits and Components
Understanding Electronic Circuits and Components
Electronic circuits involve components designed to modify electric current. This document covers fundamental concepts, devices, and their principles of operation in electronics.
Resistors: Controlling Current Flow
Resistors are components that impede the flow of electrons. This opposition to current flow helps protect other parts of a circuit from damage due to excessive current. Resistance is measured in Ohms (Ω).

Sensores del Sistema
Sensor de Inicio de Inyección
Este está formado por un bobinado que recibe una corriente a través de la ECU (30mA) que genera un campo magnético. Este campo varía cuando el núcleo se mueve dentro del bobinado. La variación del campo es utilizada por la ECU para iniciar la inyección con precisión.
Sensor de Posición de la Corredera de Regulación
Es alimentado por el eje deslizante que se mueve para la regulación. Tiene 1 núcleo, 2 bobinas y 2 anillos. Las bobinas tienen

Technology’s Role in Our Lives
Technology makes life easier for us. We use it for fun in leisure time, and everyday objects like beds and pens are all created by technology. The technological process includes:
- Identify the problem or need
- Ideas and designers explore various solutions
- Build the object
- Verify it works correctly
The Perspective of Technology
The prospect of technology is built on three coordinated axes. Two of them are at 90° and the third is at 135° with respect to the previous two.

Windmill Report
To begin with, we start making the base of the mill, which is formed by two cardboard cylinders, one slightly larger than the other. We will join them with insulating tape to get the right shape. When we have the shape of the base done, we begin painting it with acrylic paint and let it dry.
While the mill body is drying, we start making the structure of the four blades of the mill with aluminum wire. Once we have completed each of the separate blades, we join the four blades with
