Explanation

Ultimate load is the maximum load a member can carry before failure.

It is used to design structures with a factor of safety for safety margins.

Explanation

Creep is the gradual increase in strain under a constant load over time.

Common in metals, concrete, and polymers under sustained stress.

Explanation

Centrifugal pumps are ideal for low-head, high-flow applications.

They efficiently move large volumes of water at moderate pressures.

Explanation

Laying pipes at least 75 cm deep protects them from surface loads and freezing.

Ensures durability and uninterrupted water supply.

Explanation

Curing for 7 days ensures proper hydration of cement in plaster.

It prevents cracks and improves strength and durability.

Explanation

Adding water to quick lime (CaO) produces slaked lime (Ca(OH)₂).

This process is called slaking and is exothermic.
