Cylindered: meaning, definitions and examples

Etymology

• The word 'cylinder' originates from the Greek word 'kulindros,' meaning 'roller' or 'to roll.'
• It was first used in the English language around the 15th century when geometry became more popular.
• The suffix '-ed' indicates a condition or quality, pointing to objects defined by their cylindrical shape.

Mathematics

• A cylinder has two circular bases connected by a curved surface; it’s a common geometric shape studied in math.
• The volume of a cylinder can be calculated using the formula πr²h, where 'r' is the radius and 'h' is the height.
• Cylinders are used in real life, found in objects like pipes, cans, and rolls of paper!

Engineering

• Cylinders in engineering are crucial for designing engines, where they help in compressing gases for power generation.
• Many structural designs incorporate cylindrical shapes for better weight distribution and stability.
• Hydraulic cylinders are used in machines to move parts up or down, showcasing the shape's practical utility.

Art & Design

• In sculpture, cylindrical forms are often used to create abstract or modern art pieces.
• Cylinders influence architecture, seen in columns and towers providing both strength and aesthetic appeal.
• Many musical instruments, like drums, have cylindrical shapes that influence how they produce sound.

Science

• In biology, some cells and organisms have cylindrical shapes, which help in movement and structure.
• Many bacteria are rod-shaped, which is a type of cylinder, playing a crucial role in ecosystems.
• In physics, cylinders are studied in mechanics to understand rotational motion, like how wheels work.
