Hydraulic systems utilize Pascal's principle by transmitting pressure from one cylinder (called the primary) to another (called

Svetradugi [14.3K]

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

$A=\frac{\pi*d^{2} }{4}$ 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

$P=\frac{W}{As}$

We replace $P=\frac{W}{As}$ in equation 1:

$Fp=\frac{W}{As} *Ap$

$Fp=\frac{W}{\frac{\pi*d_{s}^{2} }{4} } *\pi *\frac{d_{p^{2} } }{4}$

$Fp=W*\frac{d_{p}^{2} }{d_{s}^{2} }$

$Fp=2200*\frac{2,1^{2} }{26^{2} }$

$Fp=2200*\frac{4.41}{676}$

$Fp=14.35kg$

Calculation of Fp in Newtons (N):

$1kg=9.8N$

$Fp=14.35kg*\frac{9.8N}{kg}$

Fp=140.63N

8. What variables shift both the long-run and short-run aggregate-supply curves?

vfiekz [6]

Variables shift both the long-run and short-run aggregate-supply curves are productivity, labor Wage Costs and taxes and other costs.

<h3>What is aggregate-supply?</h3>

The entire quantity of goods and services that enterprises in a national economy intend to sell during a certain time period is known as aggregate supply

Variables shift both the long-run and short-run aggregate-supply curves are ;

1. Productivity

2. Labor Wage Costs.

3. Taxes and other costs -

4. Material Prices.

5. Size of labor force.

6. Stock of Capital.

Hence, variables shift both the long-run and short-run aggregate-supply curves are productivity, labor Wage Costs and taxes and other costs.

1) What is the power in horsepower of a 100 watt light bulb? What is the power in kilowatts of a 200 horsepower engine?

Yuki888 [10]

1). Use the definition 1 Horsepower = 746 watts

100 watts = (100/746) HP = <em>0.134 Horsepower</em>

2). Use the definition Power = (work done) / (time to do the work)

and the definition Work = (force) x (distance moved)

(3,000 N x 5 m) / second

= (3,000 x 5 N-m) / second

= (15,000 joules) / second

= 1<em>5,000 watts</em>

3). Use the definition Power = (work done) / (time to do the work) , and the definition Work = (force) x (distance moved) , and the 'customary' definition of 1 Horsepower = 550 foot-pounds per second.

Let the answer ... the number of gallons ... be called ' G ' until we know what it actually is.

Weight of water lifted in 1 minute = (G gallons) x (8.34 pounds/gallon)

The distance it's lifted = 30 feet

Work done in 1 minute = (force x distance) = (8.34G x 30) foot-pounds

In just a moment, we're going to need this in seconds:

Power = (8.34G x 30 foot-pounds/minute) x (1 minute / 60 seconds)

Power = (8.34G x 30/60) (foot-pound-minute/minute-sec)

Power = 4.17G foot-pound/sec

The power = 1/2 Horsepower = 225 foot-pounds / sec

So finally, 225 = 4.17G

Divide each side by 4.17, and we have

G = (225/4.17) gallons

<em>G = 53.96 gallons</em>

I really should check this over, but I've had it up to here with gallons, feet, horsepower, and pounds, so I'm not gonna do it. Read my lips. It is what it is. I stand or fall by my answer. What could go wrong ? !
