TO CRANK UP A DISELE ENGINE
Dec 29, 2021 | Uncategorized
AIM ; to crank up a diesel engine
REQUIOREMENTS : a diesel engine , a crank , diesel, oil
PROCEDURE : 1) to start the diesel engine first check if there is diesel or not if not then fill it up
2) then check and if not then fill the oil up
3) start the cranking the engine with the crank at the rear rotating part
4) start turning the handle and at optimum speed i.e. when you get enough momentum
5) flick the switch and remove the crank
6) the diesel; engine comes to life and starts 7) to stop the engine there would be a small fuel injector at the bottom of the diesel engine push it and then it would stop fuel injection stopping the engine
TO9 MEASURE THE THICKNESS OF THE WIRE
Dec 29, 2021 | Uncategorized
AIM : to determine the gauge of the wire / to determine the thickness of wire
REQUIREMENYTS : a gauge meter , wire whose thickness has to be determined
PROCEDURE : 1) take the wire to be measured then take one strand of that wire and pass it through the small gap gives in the gauge meter
2) the point through which the wire strand passes through easily is the gauge of the wire
3) then count how many strands of wire are there in the wire
4) then while telling people we say the no of strands first and then the gauge of the strand
FUN FACT : greater the no of the gauge thinner the wire gets
