Question 28 AEL01 - Assistant Engineer - Limited

The Correct Answer is D **Explanation for Option D ("R"):** In the context of the illustration (MO-0112, likely depicting a piece of heavy equipment or a chute/hopper), the label "R" typically points to the component designed to absorb abrasion and impact from moving material. This protective layer, known as the **wear liner** (or lining), is intended to be sacrificial and replaceable, shielding the main structural components from damage. **Why Other Options Are Incorrect:** * **Option A ("G"):** Label "G" generally indicates a structural part of the assembly, such as a **side wall, back plate, or frame member**, which the wear liner protects, but it is not the wear liner itself. * **Option B ("N"):** Label "N" often refers to a smaller, specific component essential to the assembly but not the primary wear surface. This could be a **fastener (bolt or pin), a bracket, or an adjustment mechanism**. * **Option C ("P"):** Label "P" commonly points to another major structural element, perhaps the **front lip, discharge chute opening, or a stiffener bar**, rather than the replaceable protective wear liner.
