Steel Sitemas & Glued Laminated Timber: Benefits & Properties
Steel Sitemas: Pros and Cons
Pros: Simple concept using tubes and spheres, economical for covering large spans, lightweight, rigid, and highly resistant. They are statically very resistant, require few elements, and steel allows great freedom in design. They can eliminate structural side mount elements, allowing easy and quick workforce reduction, and allow positioning of auxiliary elements and passage facilities.
Cons: Difficulties in realizing and calculating these structures. For large dimensions,

Understanding Earth’s Climate
An elliptical orbit means that the solar energy received will be lower at the moments of greatest distance from the Sun than in closer proximity.
Geoastronomic Zones
Tropical Zone: Located within the tropics and divided in half by the Equator.
Temperate Zone: Located to the north, between the Tropic of Cancer and the Arctic Circle, and to the south, between the Tropic of Capricorn and the Antarctic Circle.
Polar Zone: Located between the Arctic Circle and the North Pole,

Iron Extraction and Steel Production
Iron Ore Extraction Process
The process begins with the extraction of iron ore from the mine, where all the raw material is collected. Once extracted, the ore is transported to a processing area where it is crushed into a fine, dust-like consistency.
This fine mineral powder (along with its impurities) is then transferred to a series of trays equipped with rotating paddles and water. This step aims to separate the earth and isolate as much iron-rich material as

Relief Configuration of the Iberian Peninsula
The configuration of the Iberian Peninsula’s relief is characterized by three basic features:
- Massive Form: This is due to the peninsula’s large width and generally straight coastline, with few significant indentations. This limits the influence of the sea inland.
- High Average Altitude: At 660 meters, this is due to the presence of high mountains. The interior of the peninsula is composed of an extensive upland core, the Meseta Central (Plateau).
- Peripheral
Renewable Energy Sources: Untapped Potential
Hydraulic Power
Hydropower is generated by the falling mass of water to save a difference in level. Currently, it is used to generate electricity in power plants. Reservoirs and dams are associated to retain the water and create the necessary gap for the fall of the water.
Advantages
- Minimum maintenance cost.
- It does not pollute.
- Favors navigable rivers.
Disadvantages
- Geographical limitations.
- High cost.
- Sometimes it creates social conflicts.
Tidal Energy
It is based on the exploitation of tidal currents.

Electrical Circuits
Electric current is formed by electrons jumping from one atom to another, and this movement generates electricity.
Voltage is the potential difference that makes the electric current flow through a conductor. A potential difference, tension, or voltage must exist for electric charges to move through a conductor in a given time.
Ohm’s Law
- Current = Amps = I
- Voltage = Volts = V
- Resistance = Ohm = R
In a continuous electric circuit, electrical power is produced by the movement of electrons.
