Hello,
I'm evaluating a formula to which I get and answer that is in a complex number.
The number has over 20 digits which is a little difficult to read, thus would like to change it to exponent form. I have beening trying to-do this with the Format > Results options, but with no sucess...
Glad to see there is humor, I`m wishing the O-Ring came with an ON\OFF switch, but alas !! It is quite an unusual application, I agree, but hey thats what makes engineering fun.
First I need a seal for which the ORing is there doing it`s normal job, then I need to remove this sealing point...
To clarify, I have a piece of equipement\assembly I`m testing. I would like to remove a sealing point [Oring] without dis-assembling the equipment.
I think I have three options to stop this seal working -
1. Drill through the steel to the ORing.
2. Use excessive heat to deteriate the ORing...
I tried acetone with a NBR rubber, but I just found it swelled pretty serverly, thus I`m guessing it would just improve the seal [in the short period of time I`m using it] not what I`m looking for.
I could use heat, but I really want to achieve distruction of the seal through chemical means ...
Trying to see if there is anyone out there that is aware of a fluid that will degridate the rubber in an o-ring seal [say NBR].
I`m not looking for the oring to swell, infact the opposite, be eaten !! Thus that the seal provided by the oring will be lost ....
Anyone any ideas ?? I`m told my...
