Which of the following terms describes a force acting from wind pressure?

The term that describes a force acting from wind pressure is uplift. In the context of solar installations and other structures, uplift refers to the upward force exerted by wind on a surface. When wind flows over a solar panel or any other flat surface, it creates differences in pressure, leading to a lifting effect that can potentially detach or displace the structure if not adequately secured. Understanding uplift is crucial in designing solar panel systems, especially in areas prone to high winds, as it affects the structural integrity and safety of the installation.

Other terms, while related to different types of forces within structures, do not specifically describe the force generated by wind pressure in a vertical direction. Compression refers to the squeezing force, tension relates to the pulling force, and shear involves forces that act parallel to a surface or section. Each of these forces plays a role in structural analysis, but uplift is the specific term for the upward forces caused by wind pressure.
