A
- Apse: A semi-circular, domed chapel that stands at the head of a temple.
- Arch: A curved structure that serves to bridge a gap between two walls or pillars.
- Transverse Arch/Ribs: These serve to support a barrel vault, reinforcing it and dividing it into segments or sectors.
- Wall Arch: Arches arranged parallel to the longitudinal axis of a church’s nave, connecting it with the aisles.
- Architrave: The bottom part of the entablature, resting on the supports and

Computer Basics
Secondary Memory
Secondary memory is a storage location other than the main memory. It can store and retrieve all types of information when needed without having to keep it in the main memory.
Kilobyte
A kilobyte is 1024 bytes.
Operating System
The operating system is the set of programs or software installed on your computer to control the operation of all physical devices connected to it, as well as all application programs.

Master Cylinder and Separate Braking Circuit Explained
Master Cylinder Operation
The brake master cylinder is responsible for providing adequate fluid pressure to the wheel cylinders, which in turn produce the surface application on the front wheels. The master cylinder receives brake fluid from a tank attached to it and can transfer it through conduits to the wheel cylinders. Inside the cylinder, a piston slides, fitted with a rubber cup housed in a groove. This cup performs the necessary sealing between the piston and the cylinder. A washer marks the

Engine Oil Classification
Classification by Conditions of Service
Oils are classified in laboratories based on their performance under various service conditions.
Classification by Viscosity
The SAE (Society of Automotive Engineers) classification relates oil viscosity to temperature. It consists of 10 grades:
- Six grades from 0 to 25, followed by the letter “W” (Winter), indicate cold-start performance.
- Four grades from 20 to 50 indicate the oil’s viscosity at operating temperature (100 degrees Celsius)
Feedwater ESRD Boiler with Intermediate Reheat Steam
The main feature of this boiler is that it is equipped with a heating system using steam. The purpose of global power generation through expansion is to work with dry steam at high pressure. To obtain dry steam, the expansion process involves initial steam heating, which can be done in two stages. In this first phase of superheating, there will be a relatively small increase in temperature. As the system operates at high pressure, the steam temperature before reheating is close to the critical temperature

Types of Cams and Followers
Cams are rotating or sliding pieces in a mechanical linkage that drive follower components with a specific motion. The main types of cams include:
- Radial or Disc Cams: These have a contour on the surface of a rotating disc to guide the follower.
- Cylindrical Cams: These feature a cam profile on the surface of a cylinder.
- Translating Cams: These cams move in a straight line rather than rotating.
Followers are components that are driven by the cam to perform specific motions.
