14. Get the formula which shows torque necessary to rotate the shaft of the journal bearing shown below. How much is the coefficient of friction on the circle with radius R? (hint: get friction force due to the fluid at radius R) 15. What are possible measures to reduce the friction of journal bearing (plane bearing) shown in question 14? What kinds of precaution to be taken before taking the measures? 16. Answer 3 types of solid lubricant and explain the mechanisms of each type of solid lubricant. 17. Answer 5 major functions of lubricant oil. 18. Answer 3 major additives for practical oil. Viscosity n fluid [Pa s] V [m/s] C [m] R[m] Wi[N] EE Journal bearing Length: L [m] 14.
