Determine the period of rotation of the rotor of the helicopter, if it makes 400 revolutions in 20 seconds.
| June 15, 2021 | education
The period of rotation of the rotor of the helicopter is calculated by the formula:
T = t / N, where t is the rotation time of the body (t = 20 s), N is the number of revolutions of the helicopter rotor (N = 400 rpm).
Let’s calculate the rotation period:
T = t / N = 20/400 = 0.05 s.
Answer: The period of rotation of the rotor of the helicopter is 0.05 s.
