Understanding Hard Disk Partitions and File Systems
Hard Disk Controller
An electronic structure that controls mechanical devices.
Physical Structure of the Hard Drive
It is composed of disks or magnetic surface plates.
Partitions
Concept and Reasons for Multiple Partitions
Operating systems work with logical drives, not physical units. Each hard disk can have multiple logical drives, called partitions.
- Organizational Reasons: Allows for better file organization.
- Multiple Operating Systems: Enables installation of multiple OS on a single drive.
- Efficiency
Introduction to Mechanical Systems and Machine Elements
Mechanical Systems (Static Machines)
Concept 1: Machine
A machine is a device that performs work and is devoted to the transformation of energy.
Concept 2: Mechanism
A mechanism is a set of components that serve to guide, transmit, and modify movement.
Concept 3: Design
Design is both functional and aesthetic and is subject to three forces: static, kinematic, and dynamic. It determines if a machine can carry out its intended function.
Equilibrium of Material Points and Rigid Bodies

Conformation by Merger
Types of Conformation by Merger
Conformation by merger involves heating a material to its melting point, transforming it into a liquid, and then pouring it into a mold. After cooling and solidifying, the material is extracted from the mold. The following factors are considered during the emptying process:
- The mold must withstand high temperatures without deforming.
- The mold should allow for homogenous solidification to prevent deformation of the final product.
- Molds must have openings
Introduction to Simple and Complex Machines
Machines
Definition
A machine is a set of parts or organs coupled together, allowing direct or regulated action of a force with the goal of performing a job.
Components
A machine is formed by the structure and mechanisms. The mechanisms are coupled to each piece.
- Structure: The bench, supports, feet, frame, etc.
- Mechanisms: The axles, wheels, guides, pulleys, gears, crank, etc.
Types of Movement
The types of movement that a machine makes are:
- Straight: The move follows a straight-line trajectory, both vertically

ITEM 4: AROUND MACHINING PROCESSES
Production of Round Parts
Small parts: Screw hinge mount gafas.
Large parts: Rollers, rolling rings of wind generators.
Method of Work
Work part rotation. Turning raw billet. Turning of parts made with other processes (casting, forging, etc.).
The tool moves by removing material and forming the desired shape.
Major Movements
Feed Rate (f) [mm/rev]
Is the displacement of the tool during a swivel around the workpiece.
Depth of Cut (d) [mm]
Half of the difference between the

Properties of Fluids
Liquids
In hydraulic circuits, an incompressible fluid like oil is used to transmit power. Other liquids, such as water, can also be used. Liquids have a definite volume and are not easily compressed.
Gases
Pneumatic circuits utilize compressible fluids, primarily air. Air, being a mixture of gases, behaves as a single gas with no definite shape or volume. It conforms to the shape of its container.
Pressure
Fluids exert force on the walls of their containers. This force per unit
