Solução

Vp = √2 Veff = √2 24V = 33,94 V

Velocity min:  T = 5 div * 40 ms /div = 200 ms = 0.2 s

f = 1 / T = 1 / 200 ms = 5 Hz

Velocity max:  T = 7 div * 10 ms / div = 70 ms = 0.07 s

f = 1 / T = 1 / 70 ms = 14.29 Hz

One shaft revolution corresponds to 4 periods

=>  Tshaft = 4 * 0.2 s = 0.8 s velocity min. bzw. 4 * 0.07 s = 0.28 s velocity max.
