1. a. Only major materials and components.

Only the major materials and components are include as direct materials because these are the materials that directly needed for production.

b. Only hourly production workers (aka assembly workers).

The direct labor has to be those people who are directly involved in production which in this case is the assembly workers. Managers and Supervisors are not integral so are not direct labor.

c. Both big items that cannot be traced (e.g., factory rent) and small items that are not worth tracing (e.g., glue, grease).

All other items involved in production should be included as manufacturing overheads including big items and small items that cannot be traced.

2.

Rent for the factory building ⇒ Manufacturing Overhead (OH).

Cost of engines used in production ⇒ Direct materials (DM).

Depreciation on production equipment ⇒ Manufacturing Overhead (OH).

Cost of lubricant used in production. ⇒ Manufacturing Overhead (OH).

Production supervisor's salary. ⇒ Manufacturing Overhead (OH).

Assembly workers' wages. ⇒ Direct Labor.
