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
1 answer:
Artyom0805 [142]3 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.

A light ray moving at a 54.3 deg
MrMuchimi

Answer:

45.25^{\circ}

Explanation:

Applying Snell's law

n_1sin\theta_1 = n2*sin\theta_2\\1.33*sin(54.3) = 1.52*sin\theta_2\\sin\theta_2 = 1.33*0.81208353/1.52 = 0.71057\\\theta_2=sin^{-1} (0.71057)\\\theta_2 = 45.25^{\circ}

In a hydraulic lift, if the pressure exerted on the liquid by one piston is increased by 100 N/m2 , how much additional weight c
shepuryov [24]

Answer:

The additional weight and mass needed for lifting the other piston slowly is 2500 N and 254.92 kg, respectively.

Explanation:

By means of the Pascal's Principle, the hydraulic lift can be modelled by the following two equations:

Hydraulic Lift - Before change

P = \frac{F}{A}

Hydraulic Lift - After change

P + \Delta P = \frac{F + \Delta F}{A}

Where:

P - Hydrostatic pressure, measured in pascals.

\Delta P - Change in hydrostatic pressure, measured in pascals.

A - Cross sectional area of the hydraulic lift, measured in square meters.

F - Hydrostatic force, measured in newtons.

\Delta F - Change in hydrostatic force, measured in newtons.

The additional weight is obtained after some algebraic handling and the replacing of all inputs:

\frac{F}{A} + \Delta P = \frac{F}{A} + \frac{\Delta F}{A}

\Delta P = \frac{\Delta F}{A}

\Delta F = A\cdot \Delta P

Given that \Delta P = 100\,Pa and A = 25\,m^{2}, the additional weight is:

\Delta F = (25\,m^{2})\cdot (100\,Pa)

\Delta F = 2500\,N

The additional mass needed for the additional weight is:

\Delta m = \frac{\Delta F}{g}

Where:

\Delta F - Additional weight, measured in newtons.

\Delta m - Additional mass, measured in kilograms.

g - Gravitational constant, measured in meters per square second.

If \Delta F = 2500\,N and g = 9.807\,\frac{m}{s^{2}}, then:

\Delta m = \frac{2500\,N}{9.807\,\frac{m}{s^{2}} }

\Delta m = 254.92\,kg

The additional weight and mass needed for lifting the other piston slowly is 2500 N and 254.92 kg, respectively.

A golf ball is launched horizontally at a speed of 11 meters per second and a high of 6.4 m above the ground. How long will it t
Serjik [45]

The answer is A.

t = ( 2h / g )^1/2 = ( 2 x 6.4 / 9.8 )^1/2 = 1.14s
