What type of window operates using a crank mechanism?

• A. Double-hung window
• B. Casement window
• C. Sliding window
• D. Awning window

Answer: (B)

A casement window operates using a crank mechanism, which is a distinctive feature of this type of window. The crank allows the window to be opened outwards, either to the left or to the right, providing the ability to control airflow effectively. This mechanism makes it easier to open larger windows that may otherwise be difficult to manage by hand, especially in hard-to-reach places. In contrast, a double-hung window opens vertically with two sashes that slide up and down, and a sliding window glides horizontally along a track. An awning window, while also hinged, typically opens from the bottom outward, but it has a different operational design and is usually not operated by a crank. The design and functionality of the casement window highlight its strength in providing ventilation and an unobstructed view when fully opened, making it a popular choice for many residential settings.
