How can a wedge be used in construction?

A wedge is a simple machine that functions by converting force applied to its blunt end into a force perpendicular to its slope, effectively generating a splitting or separating action. In construction, wedges are commonly utilized to split materials such as wood and stone. When driven into a material, the tapered edge of the wedge forces the material apart, making it easier to break down larger pieces into more manageable sizes. This action is particularly useful for tasks such as cutting lumber for framing or splitting rocks for landscaping or building foundations.

The other options do not align with the primary purpose of wedges in construction. For instance, while a support beam provides structural integrity, it does not act in the manner of a wedge. Similarly, measuring dimensions typically involves tools specifically designed for that purpose, not wedges. Lastly, while wedges could be used as decorative elements in some contexts, this is not their primary function in the construction industry. The wedge is fundamentally about applying force to achieve separation or splitting, which is why the correct answer focuses on its role in splitting wood or stone.
