Nearly all conventional piston engines have flywheels on them to smooth out engine vibrations caused by the thrust of individual

piston firings. Why does the flywheel have this effect
Physics

Artyom0805 [142]4 years ago
7 0

Answer:

This is because, the flywheel has a very large moment of Inertia and hence sudden piston torques have negligible effect on the flywheel, but every piston combined has a significant torque. This smoothens out the vibrations.

In a cyclotron, the orbital radius of protons with energy 300 keV is 16.0 cm . You are redesigning the cyclotron to be used inst
dem82 [27]

Answer:

r_\alpha=16cm

Explanation:

The radius of the circumference described by a particle in a cyclotron is given by:

r=\frac{mv}{qB}(1)

m is the particle's mass, v is the speed of the particle, q is the particle's charge and B is the magnitude of the magnetic field.

Kinetic energy is defined as:

K=\frac{mv^2}{2}=\frac{m^2v^2}{2m}\\

Solving this for mv:

mv=\sqrt{2mK}(2)

Replacing (2) in (1):

r=\frac{\sqrt{2mK}}{qB}

For protons, we have:

r_p=\frac{\sqrt{2m_pK}}{eB}(3)

For alpha particles, we have:

r_\alpha=\frac{\sqrt{2m_\alpha K}}{(2e)B}(4)

Dividing (4) in (3):

\frac{r_\alpha}{r_p}=\frac{\frac{\sqrt{2m_\alpha K}}{(2e)B}}{\frac{\sqrt{2m_p K}}{(e)B}}\\r_\alpha=\frac{r_p}{2}\sqrt{\frac{m_\alpha}{m_p}}\\r_\alpha=\frac{16cm}{2}\sqrt{\frac{6.64*10^{-27}kg}{1.67*10^{-27}kg}}\\r_\alpha=\frac{16cm}{2}(\sqrt{3.98})\\\\r_\alpha=\frac{16cm}{2}(2)\\r_\alpha=16cm

(0.15 x g)/100 = 0.0147N. per cm. length. 
<span>Torque short end = (0.0147 x 9) = 0.1323N/cm. </span>
<span>Torque long end = ((100 - 18)/2) x 0.0147 = 0.6027N/cm. </span>
<span>Difference = (0.6027 - 0.1323) = 0.4704N/cm. </span>
<span>(0.4704/3.2) = 0.147cm. from the 18cm. mark, = 17.853cm. from the 0 end of the stick.</span>
