Understanding Machines: Types, Mechanisms, and Principles
A machine is a set of parts or assemblies, each capable of using, transforming, managing, or regulating the action of a force, muscle, or other source, to assist people in their daily work. Any machine is formed by a series of mechanisms composed of fitted parts, allowing energy to be converted into another form of energy. Tools are hand implements used for working materials. When these tools are mounted on machines that replace human action with a series of mechanical movements, it becomes a machine
Vehicle Suspension Systems: Springs, Shocks, and More
Vehicle Suspension Systems
Springs
Formed by a cylindrical rod (10 to 14mm), made of special steel and helicoidal in shape. They exert a force; when the length decreases, the force increases. Upon cessation of force, they return to their initial state. They have a poor ability to store energy, so they need a damper to absorb the spring’s reaction.
Crossbows
Constructed of elastic steel, they have a weak performance in elasticity. They are united towards a bolt and clamps.
Torsion Bars
Solid bars made

Computer Security Fundamentals
Security: The characteristic of a system indicating it is free from danger, harm, or risk and is somehow infallible. Computer Security: A set of actions, tools, and devices needed to provide a computer system with confidentiality, integrity, and availability. Reliability: The probability that a system behaves as expected.
Objectives of Security
The core objectives are confidentiality, integrity, and availability. In a computer system, the following must be protected:
- Hardware,
Semiconductor Devices: Diodes, Thyristors, and Transistors
Bias
In this polarization, negative atoms are attracted by the positive, and the negative by the positive, i.e., there would be a reversal of the current.
Zener Diode
This type of diode works like a normal one, but when reverse biased, it allows current to flow from a particular value of the bias voltage. This diode has a stabilizing function when the value of this variable exceeds the reverse bias. Conduction occurs in the opposite direction to establish a current through the Zener, and the resistance

Storage Units: Hard Drives and Floppy Disks
General storage units can permanently store data or programs without needing power. Examples include hard disks and DVDs.
Physical and Logical Structure
The physical structure refers to how the storage medium is divided and where information is stored. It is created during manufacturing. The logical structure is how the information is saved and organized, divided into several zones.
Floppy Disks
A floppy disk is a flexible or floppy magnetic storage medium
