AI Thread Summary
Angular velocity does not influence the calculations for the size and placement of correction weights in rotor balancing. Higher angular velocities increase the forces on bearings, but this does not affect the mathematical accuracy of the correction weight placement. Properly calculated correction weights will eliminate rotor imbalance, ensuring that the forces on bearings remain consistent regardless of angular velocity. Therefore, achieving balance is independent of the rotor's speed. Accurate calculations are essential for effective rotor balancing.

concerning a rotor with an imbalance, how does the angular velocity of the rotor affect calculations about the size and placement of the correction weight?

angular velocity doesn't affect it
 
the higher the angular velocity - the greater forces on bearings. if you calculate the size and placement of the correction weight mathematically accurate, a rotor will have no imbalance, so force on bearings won't be dependent on angular velocity.
 
Thread 'What type of toilet do I have?'
I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...
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...
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...
