Efficiency = (output / input) x 100
Efficiency = 54000/600
efficiency = 90%
Answer:
We have to take the two axes of coordinates, the X axis & the Y axis, and perform the equation of sum of forces on each of the X & y axes. In order to find the value of the respective forces. We can also perform summations of moments around a given point to find unknowns in deduced equations.
Explanation:
A free body diagram gives us a summary of the forces acting on a body. These forces can be equal to zero. Or equal to the product of its mass by acceleration.
Although in some cases special attention should be paid to the movement of the body by such forces, for example if the movement is at constant speed, the acceleration will be equal to zero. Therefore the sum of forces will be equal to zero when the speed is constant.
Finally we have to take the two axes of coordinates, the X axis & the Y axis, and perform the equation of sum of forces on each of the X & y axes. In order to find the value of the respective forces.
We can also perform summations of moments around a given point to find unknowns in deduced equations.
In the attached image we can see a beam which is subjected to loads, and performing a summation of moments around the pivoting point equal to zero (the beam is in balance) we can find the value of force F.
Here is the energy that is left after the quantity of energy is transformed: 750 j of electrical energy is changed into 400 j of kinetic or mechanical energy, which is then turned into 0.32 j of efficient energy.
To run the fan, electrical energy is utilized.
Here, under the specified circumstances, 750 J of electrical energy is utilized to operate the fan, which is transformed into 400 J of kinetic energy. As a result, 350 J of energy is wasted due to various frictional and resistive losses.
Therefore, we may conclude that only 400 J of the 750 J available energy is used to power the fan, with the remaining energy being wasted as a result of friction.
Additionally, we can state that this fan's effectiveness will be
n = Useful ÷ Total
n = 400 ÷ 750
n = 8 ÷ 25
n = 0.32
