A mechanical bender is applicable for making bends in which type of conduit?

A mechanical bender is specifically designed for bending metal conduit types, and it excels in shaping materials like electrical metallic tubing (EMT). EMT is typically lightweight, easy to work with, and can be bent with machines to achieve smooth, consistent curves, making it ideal for projects involving wiring systems.

When considering the types of conduit listed, EMT stands out as the most appropriate choice for the application of a mechanical bender. Other materials, such as PVC or rigid conduit, generally require different bending techniques or equipment. PVC, for example, is typically bent using heat or specialized fittings rather than mechanical benders, while rigid conduit is often not bent due to its heavier and more robust construction. Additionally, the mention of IMC is less relevant here, as it refers to intermediate metal conduit, which is also suitable for hand or mechanical bending but is not the sole focus.

Thus, the suitability of EMT for mechanical bending aligns with its physical properties and common practices in the electrical trade, reinforcing why this option is the right answer.
