Answer:
The force to be applied on the primary piston is 140.63 N.
Explanation:
To solve this problem we apply the following formulas:
Pascal principle: F=P*A Formula (1)
F=Force applied to the piston
P: Pressure
A= Piston area
Formula (2)
d= piston diameter
Nomenclature:
Fp= Force on the primary piston
Fs= Force on the secondary piston
Ap= Primary piston area
As= Secondary piston area
W= car weight
Calculation of the force Fp necessary to support the weight of the car.
Pascal principle: Fp=P*Ap (Equation1)
In (Equation1) we know Ap and we don't know P.
Pressure calculation:
We apply Newton's first law for a balanced Secondary piston -automobile system
Newton's first law: ∑F=0
W-Fs=0
W=Fs
W=P*As
We replace in equation 1:
Calculation of Fp in Newtons (N):
Fp=140.63N
