Motion Transmission and Conversion Mechanisms
Transmission of Motion
Gears
A gear is a rotating component within a transmission device that transmits rotational force. Unlike pulleys, gears have teeth that mesh with other gear teeth, ensuring complete force transfer without slippage. Gears can modify speed, torque, and direction of force. They are essential simple machines, commonly meshing with other gears or compatible toothed devices like racks.
A key feature of gears is their ability to create a mechanical advantage when gears of different

Identify Opportunity
Identifying a need or problem is the first step to gathering information. Background research helps us understand how others have addressed similar situations. We can consult books, magazines, newspapers, the internet, or personal interviews.
Design
Once an opportunity is identified, we design the new product. This creative stage involves imagining and conceptualizing. Product design includes researching materials, determining shape and size of components, and planning assembly.

Energy Sources
Renewable Energy
Renewable energy sources can be used continuously. Examples include:
- Hydraulic Energy: Water moves wheels and turbines, generating power.
- Wind Energy: Wind turns the blades of wind turbines.
- Biomass Energy: Organic waste is used as fuel.
- Solar Energy: Sunlight heats solar cells, producing electricity.
- Geothermal Energy: Heat from the Earth’s interior is harnessed.
Non-Renewable Energy
Non-renewable energy sources are finite and cannot be regenerated. Examples include:
- Nuclear
Residential Complex Lighting Upgrade in Castro Urdiales
Background
We propose a project to improve the lighting electrical installation of a residential complex. This project aims to optimize the lighting in the complex’s recreational areas, including gardens, tennis courts, and the pool, to achieve greater energy savings. The complex is located in Castro Urdiales, a coastal town in Cantabria, known for its tourism and proximity to Bilbao. The area comprises 4000m², with an 800m² built area, landscaped lawns, trees, a 12×6 community pool, two 23×8 tennis

ITEM 1: Economic Sectors and Activities in Electricity and Electronics
Firms can be classified according to various criteria. Looking at the economic sector, we can distinguish:
a) The primary sector includes companies involved in obtaining basic goods (raw materials) directly from nature, e.g., agriculture, livestock, fisheries, and forestry.
b) The secondary sector transforms products from the primary sector, e.g., factories.
c) The tertiary or services sector distributes goods and meets needs not

Technical Drawing
Perspective
Cavalier Perspective: Two perpendicular axes create a sense of depth with a third, inclined axis.
Isometric Perspective: Axes are separated by equal angles. Piece measurements are maintained, but angles between principal axes are deformed. Parallel lines are preserved.
Drawing from Known Perspectives
Compositional Methods: Extend parallel to the relevant axis (X for vertical, Z for depth) to obtain the projected figure. Locate surfaces originating from vertices to complete
