What is a Jesus Nut?
You need Google for this assignment:
<---  Have a look at the image on the left about the basic parts of a helicopter rotor. The internet can be of great help to overcome gaps in your English knowledge. In the image you see the ‘swash plate assembly’

A quick look-up on Google explains what it does:

A swash plate is a device that translates input via the helicopter flight controls into motion of the main rotor blades. Because the main rotor blades are spinning, the swash plate is used to transmit three of the pilot's commands from the non-rotating fuselage to the rotating rotor hub and main blades.

Fun fact: The Jesus nut
Jesus nut, or Jesus pin, is a slang term for the main rotor retaining nut which holds the main rotor to the mast of some helicopters, such as the UH-1 Iroquois helicopter; or more generally is any component that represents a single point of failure with catastrophic consequences.
 
The term Jesus nut may have  been coined by American soldiers in Vietnam; the Vietnam War was the first war to feature large numbers of soldiers riding in helicopters.

If the Jesus pin were to fail in flight, the helicopter would detach from the rotor, and the only thing left for the crew to do would be to "pray to Jesus."
