AI Thread Summary
To calculate the torque needed for operating 20 agitators, the total torque is determined by adding the individual torque requirements. Each agitator requires 5 Nm, leading to a total of 100 Nm for all 20. Additionally, it’s important to account for extra torque needed to accelerate the rotational masses from 0 RPM within the desired time frame. This additional torque must be factored into the overall calculation. Understanding these components is crucial for selecting the appropriate motor.

Hi Guys and Girls, I new to here. I am Designer and recently I am studying the torque of a motor needed to turn a set of 20 agitators by using a belt. Let say each of the agitator have needed 2Nm to operate, so if I use a motor to operate 20 agitators how many of torque is needed. I have no idea on it. Can you give me some ideas? Thank you!

Hello Eugym, welcome to PF :smile: !

In the picture it says 5 Nm per agitator !
Anyway, in principle you can just add up the torques, so you would end up with 40 Nm for your case, or 100 Nm for the case as shown in the picture.
 
I also thinking in this way. Ok, I will try hard on it. Thanks for your opinion!
 
You also need to add sufficient torque to accelerate all of the rotational masses from 0 RPM within the time required. This will be in addition to the 20x5 Nm torque.

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Thread No-Go plug gage allows 3 turns to enter. That's too many!'

After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
