Theory of Machine A friction circle is a circle drawn when a journal rotates in a bearing. Its radius depends upon the coefficient of friction and the Angular velocity of journal Radius of journal Magnitude of the forces on journal Clearance between journal and bearing Angular velocity of journal Radius of journal Magnitude of the forces on journal Clearance between journal and bearing ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The factional torque for square thread at the mean radius r while raising load W is given by T = W.r tanα T = W.r tan(φ - α) T = W.r tan(φ + α) T = W.r tanφ T = W.r tanα T = W.r tan(φ - α) T = W.r tan(φ + α) T = W.r tanφ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The fundamental equation for correct steering is (where φ and α = Angle through which the axis of the outer wheel and inner wheel turns respectively, c = Distance between the pivots of the front axles, and d = Wheel base) cosφ - sinα = c/b tanφ + cotα = b/c cotφ - cotα = c/b sinφ + sinα = b/c cosφ - sinα = c/b tanφ + cotα = b/c cotφ - cotα = c/b sinφ + sinα = b/c ANSWER DOWNLOAD EXAMIANS APP
