Question

What is the speed of rotation of the driver gear if it has 700 teeth and drives another gear with 350 teeth? The speed of rotation of the driven gear is 210 rpm.

A. 105 rpm
B. 140 rpm
C. 210 rpm
D. 420 rpm

Answer 1

To calculate the speed of rotation of the driver gear, we can use the formula: Speed of rotation of the driver gear = (Number of teeth on the driven gear / Number of teeth on the driver gear) * Speed of rotation of the driven gear. Plugging in the given values, we find that the speed of rotation of the driver gear is 105 rpm.

Step-by-step explanation:

To calculate the speed of rotation of the driver gear, we can use the formula:

Speed of rotation of the driver gear = (Number of teeth on the driven gear / Number of teeth on the driver gear) * Speed of rotation of the driven gear

In this case, the number of teeth on the driven gear is 350, the number of teeth on the driver gear is 700, and the speed of rotation of the driven gear is 210 rpm.

Plugging in these values into the formula, we get:

Speed of rotation of the driver gear = (350 / 700) * 210

Simplifying, we find that the speed of rotation of the driver gear is 105 rpm. Therefore, the correct answer is A. 105 rpm.
