Which statement concerning a lubricating oil's viscosity and bearing loading characteristics is true? |
A) Shaft bearings associated with relatively low torque loads and high rotational speeds require a lubricating oil with a relatively high viscosity. |
B) Shaft bearings associated with relatively high torque loads and low rotational speeds require a lubricating oil with a relatively high viscosity. |
C) The viscosity requirements of a lubricating oil are not dependent on the relative torque load or rotational speed of a shaft bearing. |
D) Shaft bearings associated with relatively high torque loads and low rotational speeds require a lubricating oil with a relatively low viscosity. |
