Q: I found part of her story online, but can't find anything as to what happened to the 1000+ paper cranes she made before she died. Were they given to family members or given to a museum? Or have they been destroyed by time? I would feel terrible if all her work was destroyed by time or worse. :-(Thank you so much for answering.Peace.: Her parents buried most of the cranes with her.

Q: if someone have formula for that, one telescopic crane is lifting and i know about the boom lenght and redius,then how i can calculate the angle,if crane crane angle indicator is not working.thankyou.: Boy! You really need to get the angle indicator fixed and calibrated! There are ways to estimate, but they are inaccurate and therefore not safe, if you have not got the expierence to do it. Don't use the crane for any load close to your SWL!!! An addition: unless you want to measure your reach, i.e. the distance from the crane pedestool to your load, then you can calculate the angle, but you don't need to anymore as you now know what the distance of your lift is and therefore you can look up the SWL on your chart. Get it fixed.
