Part A Hydraulic rescue equipment

Question a
dadas principle - states that when there is an increase in rack at any point in a
jailed swimming, there will be an equal increase in compel at every other point in the container.
Meaning that pressure acts in all the directions.

Question b
* To learn Pascals principle imagine an enclosed fluid as in figure below
* The figure has two divers which moves within.
* champion(a) of the pistons has a petite cross sectional area,
* The other one has a hulky cross sectional area.
* The bear on pushes the small piston into the hydraulic fluid,
* This results that a pressure is transferred unto the larger piston.
* The pressure is the same, as per Pascals principle, on the small and large piston.
* Total FORCE = P X A
* The total force on the larger piston will be great than the total force on the smaller piston.
* The larger piston multiplies force exerted on the smaller piston.








A1 = P1 & A2 = P2
* P1 = P2(P = F )
A

* F1 = F2ORF1 = F2
A1 A2A1 A2
* Thus F2 = F1 x A2
1 A1
* Thus F2 = 2 x F1
* If A2 > A1 then F2 > F1
* Due to the area at A2 being larger, and as Pascals law just explained, the force at A2 must be bigger, thus allowing the cutters to have such a great strength.


Part B Venturi Effect

* Bernoullis precept applies to the working...If you want to get a full essay, order it on our website: Ordercustompaper.com
