A theodolite is a precision instrument used for measuring angles in the horizontal and vertical planes.

• Used in surveying and construction to measure angles and distances

• Consists of a telescope mounted on a rotating base with graduated circles for angle measurement

• Commonly used in setting out building foundations, roads, and tunnels

• Helps in determining elevations, heights, and distances between objects

The ratio of M20 grade concrete is 1:1.5:3 (cement:sand:aggregate).

• The ratio of M20 grade concrete is 1:1.5:3, which means 1 part cement, 1.5 parts sand, and 3 parts aggregate.

• This ratio is commonly used for construction of residential buildings, bridges, and pavements.

• It is important to follow the correct mix ratio to ensure the strength and durability of the concrete.

A purline is a horizontal structural member in a roof construction that supports the common rafters.

• Purlines are typically made of wood, steel, or aluminum.

• They are placed parallel to the ridge of the roof and provide support for the roof covering material.

• Purlines help distribute the weight of the roof evenly and prevent sagging or structural issues.

• Examples of roof types that use purlines include gable roofs, hip roo

A module is a self-contained unit that can be used in various systems or projects.

• Modules are often used in solar energy systems to generate electricity.

• They typically consist of multiple solar cells connected together.

• Modules can vary in size and power output depending on the specific application.

• Examples of modules include monocrystalline, polycrystalline, and thin-film solar panels.
