Quick Answer: How Do You Find Minimum Power?

What is minimum power?

This theory predicts that the most likely coalition to form in a group will be one that wins but comprises the individuals with the smallest amounts of power consistent with this outcome.


What is transferred when work is done?

Work is the measure of energy transfer when a force (F) moves an object through a distance (d). So when work is done, energy has been transferred from one energy store to another, and so: energy transferred = work done. Energy transferred and work done are both measured in joules (J).

When work done is maximum?

This means that when the force is applied on a body and the displacement of the body takes place in the direction of the force applied then work done is maximum. So when theta=0°, work done is maximum.

How do you find the minimum power output?

A joule is equal to one Newton-meter, which is the amount of work needed to move a 1 Newton force a distance of 1 meter. When you divide work by time, you get power, measured in units of joules per second. This is also called a Watt. 1 Watt = 1 Joule Sec.

What is the condition for minimum power required?

D. So the minimum power required (maximum endurance) occurs when is a maximum. Thus the minimum power (maximum endurance) condition occurs at a speed which is 3-1/4 = 76% of the minimum drag (maximum range) condition.

What is the 5 rule in physics?

The purpose of the 5% Rule is to give you the option of eliminating a vertical axis intercept. When you have a vertical axis intercept that you believe exists only because of error in your data, the 5% Rule can be invoked (if all conditions are met) and the intercept may be dropped from you mathematical equation.

What is p w t?

P = W / t. The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time.

What is the minimum work done?

ii) Work done is minimum when the Force – Displacement are perpendicular to each other.

Why is power needed?

Power required is the power or thrust that is needed to maintain unaccelerated flight for a given set of conditions i.e. constant speed and in level flight/climbing/descending/turning or any combination of these events.

What is the minimum thrust required?

Consequently we can see that the minimum thrust required occurs when L/D is a maximum. Again, since L = W, the maximum value of L/D occurs when drag is a minimum. Hence the minimum thrust required occurs at the minimum drag flight condition which is the same as the maximum L/D flight condition.

How do you find power?

Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.

What is average power formula?

If the resistance is much larger than the reactance of the capacitor or inductor, the average power is a dc circuit equation of P=V2/R, where V replaces the rms voltage. An ac voltmeter attached across the terminals of a 45-Hz ac generator reads 7.07 V.

Why is there a minimum energy?

The photon must have a minimum energy because otherwise energy will not be conserved. Also, the photon must be near a nucleus because linear momentum also has to be conserved. The decay will happen only if these two conditions are satisfied.

How lift is calculated?

The lift equation states that lift L is equal to the lift coefficient Cl times the density r times half of the velocity V squared times the wing area A. For given air conditions, shape, and inclination of the object, we have to determine a value for Cl to determine the lift.

What is the formula for power output?

Electric Power PwattsAmperage IampsVoltage VvoltsP = I × V I = P / V V = P / I2 more rows

What is current formula?

Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is I = V/R.

Which state has the minimum amount of energy?

solidAll particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy.
