Answer:
The cross-sectional area of the larger piston is 392cm ^{2}[/tex]
Explanation:
To solve this problem we apply the following formula:
Pascal principle: F=P*A Formula (1)
F=Force applied to the piston
P: Pressure
A= Piston area
Nomenclature:
Fp= Force on the primary piston= 500N
W= car weight =m*g=2000kg*9.8m/s2= 19600N
Fs= Force on the secondary piston= W = 19600N
As= Secondary piston area=?
The pressure acting on one side is transmitted to all the molecules of the liquid because the liquid is incompressible.
In the equation (1)
P=F/A
Pp=Ps
Answer:
(a) k =
(b) τ = ∝
Explanation:
The moment of parallel pipe rotating about it's axis is given by the formula;
I = ---------------------------------1
(a) The kinetic energy of a parallel pipe is also given as;
k = --------------------------------2
Putting equation 1 into equation 2, we have;
k =
k =
(b) The angular momentum is given by the formula;
τ = Iw -----------------------3
Putting equation 1 into equation 3, we have
τ =
But
τ = dτ/dt = ------------------4
where
dw/dt = angular acceleration =∝
Equation 4 becomes;
τ = ∝
