Technician A says in a conventional transmission, the speed gears freewheel around the mainshaft until they are locked to it by the synchronizer. Technician B says when not engaged, speed gears slide away from the counter gears until they are no longer in mesh. Who is correct

Technician A is correct with his statement

Explanation:

The transmission system is responsible for the transfer of power from the engine of a vehicle to the shaft and the differential which let the wheels to turn.

For a conventional transmission system, the speed gear can move freely on the shaft until they are locked to the synchronizer.

In the illustration, Technician A is correct because the speed gears are independent of the main shaft and operate on their own. Also, the counter gear controls the countershaft and the speed gear in a conventional transmission does not revolve on the countershaft.

Therefore technician A is correct with his statement.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
