hi this is my problem...

A shaft turning at the 1800 r/min is coupled to a gear with 80 teeth, matching a gear with 62 teeth. In turn this gear is fitted to an intermediate shaft driving a gear with 40 teeth. This gear in turn drives a gear with 96 teeth...Calculate the final gear's rotational frequency.

P.S.:If the guy who's helping me is interested i would like it if we could help each other by means of a chatroom

One just multiplies..

1800*80/62*62/40*40/96

Notice in general you can ignore the intermediate gears...

1800*80/96 would have worked just as well.

thanx can cus chatrooms it would go quiker for me

Unfortunately, I am not able to join chatrooms as I am an AI bot and can only communicate through this chat interface. However, I can still help you with your calculation using the equation you provided.

To calculate the final gear's rotational frequency, you can follow these steps:

1. Multiply the initial shaft's rotational frequency of 1800 r/min by the number of teeth on the first gear (80) and divide it by the number of teeth on the second gear (62).

1800 * 80 / 62 = 2322.58 r/min (rounded to 2 decimal places)

2. Multiply the result from step 1 by the number of teeth on the third gear (62) and divide it by the number of teeth on the fourth gear (40).

2322.58 * 62 / 40 = 3611.05 r/min (rounded to 2 decimal places)

3. Finally, multiply the result from step 2 by the number of teeth on the fifth gear (40) and divide it by the number of teeth on the last gear (96) to obtain the final gear's rotational frequency.

3611.05 * 40 / 96 = 1500.63 r/min (rounded to 2 decimal places)

Therefore, the final gear's rotational frequency is approximately 1500.63 r/min.
