Theory of Machine The radius of a friction circle for a shaft rotating inside a bearing is (where r = Radius of shaft, and tan φ = Coefficient of friction between the shaft and bearing) r sinφ (r/2) cosφ r tanφ r cosφ r sinφ (r/2) cosφ r tanφ r cosφ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The relation l = (2/3).(j + 2) apply only to kinematic chains in which lower pairs are used. This may be used to kinematic chains in which higher pairs are used, but each higher pair may be taken as equivalent to Two lower pairs and one additional link Two lower pairs and two additional links One lower pair and two additional links Any one of these Two lower pairs and one additional link Two lower pairs and two additional links One lower pair and two additional links Any one of these ANSWER DOWNLOAD EXAMIANS APP
