Power of a Motor: Unleash Your Potential with Science
How can we calculate the power of a motor using force and speed?
Calculate the power of a motor if a load of 20 newton is required to move with speed of 100 rpm, while the arm length is 1 m.
A. 2000 [watt]
B. 2000 [hp]
C. 209 [hp]
D. 0.28 [hp]
Answer:
The power of the motor is approximately 209 Watts. The correct answer is none above all options.
To calculate the power of a motor, we can use the formula: power = force * velocity. In this case, the force required to move the load is 20 Newton. The speed is given as 100 rpm, which we can convert to m/s.
First, we need to convert 100 rpm to m/s by multiplying it by 2π and dividing by 60. This gives us approximately 10.47 m/s. Now we can calculate the power by multiplying the force (20 N) by the velocity (10.47 m/s).
The power of the motor is approximately 209 Watts.
