Understanding Key Building Structures and Components
Building Structures
There are three main types of building structures:
- Solid structures: Use walls made of materials like bricks, blocks, or stone to support the building.
- Frame structures: Use horizontal beams and vertical pillars made of wood, metal, or concrete to support the building and are quicker to build.
- Combination structures: Use both solid walls and a frame.
Load-bearing masonry was once common because it is strong and looks nice, but it is slow and labor-intensive to build. Frame structures

Hard Drives: Traditional Storage
The hard drive is the primary means of storing large amounts of information on a computer. It belongs to a type of memory called mass memory. Although significantly faster than other storage media, it has some disadvantages. External hard drives with USB, Firewire, or eSATA interfaces offer portability. However, even though an external hard drive is portable, it’s not always the best way to transport information because it’s composed of mobile and sensitive components

Hotel Engineering Systems
1. Cold Water Supply System
From the aquifers, the pipes have specific pressure. Engineers know the pressure at each point, so when a hotel wants to connect to the public pipe, they can do so. Once connected, we add a counter that measures the water we receive. This water goes to a tank where it is kept. Then, water goes through a pump that sends it either to the base of the building (Constant Pressure System) or to the top (Gravity Fed System) to a tank from where the water

Steam Power Plant
- The major components of this power plant are: (i) boiler, (ii) steam turbine, (iii) condenser, (iv) water feed pump, (v) electrical generator, (vi) cooling tower, etc.
- In a steam power plant, thermal energy is converted to electric energy.
- Water is supplied to the boiler through a feed water pump (1) from the water tank.
- The water in the boiler (4) is heated by transferring heat from the combustion of fossil fuel in the furnace. The boiler consists of an economizer (6) and a superheater
Types and Functions of Mechanical Couplings and Clutches
Understanding Mechanical Couplings
Durable Couplings are essential machine components used during power transmission. Their primary functions involve connecting shafts, facilitating mounting, and simplifying maintenance.
Drive Couplings
These couplings provide a direct link between two shafts, typically transmitting rotational motion. They often involve plates or screws connecting the elements, allowing for power transfer but generally not accommodating misalignment unless specifically designed to

Fire Extinguishing Installations
BIE (Fire Hose Stations)
A pressurized water fire extinguishing system comprising:
- Connection to a public water supply or fire pumping equipment.
- Network of pipes for water distribution.
- Hose reel (BIE).
Sprinklers
Individual, automatic sprinkler heads connected to a separate cold water pipe, capable of withstanding a pressure of at least 150 meters of water column (mca), and composed of:
- Water intake from the general network, independent
