Explanation

Moment of inertia represents a body’s resistance to angular acceleration about an axis.

Greater mass farther from the axis increases the moment of inertia.

Explanation

In the Bessemer process, air is blown through molten pig iron to oxidize and remove impurities.

It was one of the earliest and fastest methods for mass-producing steel.

Explanation

Newton’s law of gravitation states that the force is directly proportional to the product of the two masses.

It is inversely proportional to the square of the distance between their centers.

Explanation

A strap footing uses a cantilever (strap) beam to connect two isolated footings.

It helps balance loads when a column is close to a property line.

Explanation

Acrylic is a transparent plastic widely used for glazing in windows and skylights.

It is lightweight, durable, and offers good clarity with weather resistance.

Explanation

A rectangular R.C.C (Reinforced Cement Concrete) column requires a minimum of 6 main longitudinal bars for structural stability.

This ensures proper load distribution and confinement of concrete.

Explanation

A joist is a light, closely spaced beam arranged in parallel to support floors or low-slope roofs.

Joists transfer loads to main beams, girders, or walls.

Explanation

An inverted siphon is generally designed with three pipes (barrels) to carry discharge efficiently.

Multiple pipes help in regulating flow and allow maintenance without stopping the entire system.

Explanation

A girt is a horizontal structural member fixed between columns.

It supports wall cladding in steel and industrial buildings.
