beam of light, traveling in air(the index of refraction for air is 1), strikes the surface of mineral oil at an ngle of 30° with
the normal to the surface.( the index of refraction for this mineral oil is 1.38) What is the ngle of refraction? What is the speed of the light traveling in mineral oil?
The advantage of using a clutch brake is that it is capable of handling high load torque and ensures safety at high rotational speeds.
The motivation behind a clutch brake is to stop or slow the information shaft from turning, enabling the apparatuses to work without pounding/conflicting. This kills harm to non-synchronized transmissions, and limits the exertion required when moving from impartial into first or switch from a halt.
