Question

механическое движение от колеса 1 к колесу 2 передается с помощью ремня если угловая скорость колеса 2 равна 100 пс -1, и радиусы колёс соответственно 30 и 10 см, сколько оборотов в минуту совершает колесо 1? ответ должен быть 300 раз

Answer 1

r1/r2=30/10=3

К1=100*3=300p

Answer 2

Calculation of Wheel 1's Rotations per Minute

To calculate the number of rotations per minute (RPM) that Wheel 1 makes when mechanical motion is transmitted from Wheel 1 to Wheel 2 using a belt, we can use the formula:

RPM1 = (RPM2 * Radius2) / Radius1

Given the following values: - Angular speed of Wheel 2 (RPM2) = 100 ps^-1 - Radius of Wheel 1 (Radius1) = 30 cm - Radius of Wheel 2 (Radius2) = 10 cm

Substituting these values into the formula, we get:

RPM1 = (100 * 10) / 30 = 33.33 RPM

Therefore, Wheel 1 makes approximately 33.33 rotations per minute when the angular speed of Wheel 2 is 100 ps^-1.

Please note that the result has been rounded to two decimal places.

Conclusion

When mechanical motion is transmitted from Wheel 1 to Wheel 2 using a belt, and the angular speed of Wheel 2 is 100 ps^-1, Wheel 1 makes approximately 33.33 rotations per minute.
