PROPOSED METHODOLOGY

1. To establish coefficients of kinetic friction by the sliding block method for dry condition and for oil-lubricated condition.
2. To investigate wear by means of rotating a mild steel shaftof surface finish 1 micron at various speeds inside wooden journal bearings which are axially loaded by a weight of approximately 200 Newtons (20 kg force).
3. To use 7 types of timber.
4. To use 4 lubrication treatments - dry, greased, impregnated with old engine oil, and gravity-fed by SAE 30 mineral oil.
5. To use various values of projected bearing area, shaft angular velocity, and shaft diameter.
6. To conduct tests until significant values of wear can be measured using vernier calipers.
7. To analyse the results with the intention of producing formulae for predicting wear.
