When gasoline is burned in the cylinder of an engine, it creates a high pressure that pushes the piston. If the pressure is 100.
Marianna [84]

Answer:

\dot W=2.1074\ hp

Explanation:

Given:

  • pressure on the piston, P=100\ psi=689476\ Pa
  • diameter of the piston, d=3\ in=0.0762\ m
  • displacement of the piston, s=0.05\ m
  • time taken in the piston displacement, t=0.1\ s

<u>Now, we find the force on the piston:</u>

F=P.A

where, A = area upon which pressure acts

A=\pi.\frac{d^2}{4}

A=\pi.\frac{0.0762^2}{4}

A=0.00456\ m^2

\therefore F=689476\times 0.00456

F=3144.2638\ N

<u>we know that Power is given as:</u>

\dot W=\frac{F.s}{t}

\dot W=\frac{3144.2638\times 0.05}{0.1}

\dot W=1572.1319\ W

\dot W=2.1074\ hp

You push on the top edge of a 1.8 m tall solid circular cylinder of iron which is 4.00 cm in diameter. You push with a horizonta
Citrus2011 [14]

Answer:

\triangle x=3.2*10^-^5 m

Explanation:

From the question we are told that

Height of circular cylinder is h= 1.8m

Diameter of cylinderD=4cm=>0.04m

Horizontal Force  F=900N

Y = 10.0 *10^1^0 N/m^2 \\B = 9.0 * 10^1^0 N/m^2\\S = 4.0 * 10^1^0 N/m^2\\

Generally the formula for shear modulus is mathematically represented by

G=\frac{\tau}{\gamma}

Where

G=Shear modulus\\\tau= shear\ stress\\\gamma=shear strain

G=\frac{F/A}{\triangle x/L}

G=\frac{900/\pi r^2}{\triangle x/1.8}

4.0*10^1^0=\frac{900/\pi r^2}{\triangle x/1.8}

4.0*10^1^0=\frac{900}{\pi r^2}  *\frac{1.8}{\triangle x}

{\triangle x} =\frac{1620}{\pi r^2* 4.0*10^1^0}

\triangle x=3.2*10^-^5 m

What about a rubber band, can it change its shape? Is it a solid?
pshichka [43]

Answer:

Yes it is a solid

Explanation:

It just has unusual properties.

Does it float when you drop it? then it is not a gas.

Does it pour into any container as water does? Then it is not a liquid.

So it's a solid.

And it can change it's shape
