Understanding Plastics, Textiles, and Ceramics
Plastics
Plastics are made of materials formed by long chains containing carbon atoms.
Their Properties
They are very good electrical insulators, resistant to many chemical agents. The process of obtaining them is economical. Pieces of plastic can be manufactured cheaply. Plastics are not biodegradable.
Classification of Plastics
- Thermoplastics are those that soften when heated and can be shaped many times.
- PVC: Impermeable, flexible.
- High-density polyethylene: Rigid, resistant, and transparent.
- Low-density
Understanding Vehicle Brake Systems: Types, Functionality, and Safety
Brake Service
The brake service allows the driver to reduce vehicle speed during normal driving, enabling them to slow down and stop.
Features:
- Number of circuits: One mixed brake circuit for the front and rear channels independently.
- Force on the foot: Maximum 800 Newtons.
- Maximum pressure circuit: 20-50 Bar.
- Pedal mechanical relationship: 8:1 to 5:1.
Auxiliary Brake
The auxiliary brake complements and supports the service brake in case of failure or damage, allowing the vehicle to slow down and come to

A structure is a collection of elements arranged in an optimal way to support a body or an object. When we design a structure, we need to combine maximum strength with the minimum amount of material. This makes the construction as economical and lightweight as possible.
Types of Structures
Mass Structures
These are solid, heavy, and very sturdy structures, such as walls and dams.
Frame Structures
These are formed by columns and beams that act as supporting elements, like in buildings.
Truss Structures
These
Mastering Animation Techniques: Motion Paths, Tweens, and Tools
Key Animation Terms
- Bone Tool: A tool used to add bones into shapes or symbols.
- Armature Layer: A layer on the Timeline that contains poses.
- Root Bone: The first bone added.
- Pose: The placement of the armature.
- Head: The beginning of the bone.
Motion Path Animation
What is motion path animation?
A type of animation that has an object follow a path on a guide layer.
What type of tween is used when making a motion path?
Classic tween.
How do you add a motion guide layer?
Right-click on a layer and select Classic

Switched Access Lines
Switched access lines are those that need to establish a call between two endpoints for communication, i.e., the lines connecting each central pole from origin to destination, e.g., a phone call. The optimization of these lines requires stations to use coral switching, i.e., the two ends together with their mechanisms.
Land Lines
Switched telephone networks are guided by a physical means, usually a twisted-pair cable with two or four copper wires. RTC serves voice and data transport.

History of Robots
Research in this area began in the 1950s, promising rapid progress. However, it stalled due to seemingly simple problems. In 1960, a robot could see a tower of cubes and copy it, but the lack of common sense led it to build the tower from the top down, releasing the blocks into the air. David Freedman, recognized as one of the best U.S. science writers, documented in his book Brain Makers two major projects under development in the area of artificial intelligence.
