Depreciation on delivery trucks is not part of manufacturing overhead for producing a computer. Manufacturing overhead is also referred as factory burden, factory overhead or production overhead, which comprises of all the manufacturing costs such as electricity cost, factory supplies, factory labor (not direct one), rent, insurance, heating, water and all other energy related costs, salaries, cleaning, oiling, greasing, servicing and repairs etc.
Depreciation on delivery truck is not included in manufacturing overhead, whereas, remaining all other options are the part of it.
Manufacturing overhead are the sum of all of the indirect material, labor and any other cost which can not be identified easily with the products and units produced in the manufacturing plant. These are assigned to the every produced unit on equal basis. For example, if your overhead cost is $50000 for the last year and you have manufactured 5000 units, then by dividing $50000 by 5000 units you can get your manufacturing over head cost which is $10 per unit.
