Questions & Answers
My mountain bike rear wheels rubs against the frame. Stripped QR skewer the cause?
I had a question on this already but need to repost to clarify.
I have an alum mt bike hart tail.
When I climb uphill sometimes my rear tire rubs against the left side of my rear frame.
The odd thing is if i flip the bike upside down and shake the wheel, there is no play in it left to right at all so it's not the bearing cones or the bottom bracket as someone suggested earlier.
The one thing I did notice is that the quick release skewer looked stripped where the skewer clamps down on the frame.
The frame also looked stripped.. there were no teeth where the QR should clamp down on the frame.
I am thinking that the fact the skewer isn't biting down firmly on the frame is causing the movement when i'm straining on the uphills?
Will getting a new skewer fix this? I'm wondering that if the frame itself is stripped in terms of where the skewer bites down then is there something I need to do to fix the frame as well? It's just flat and getting thin where the skewer clamps down.
You need to fix this before you ride again. You do not want to let a bad cheap part (skewer) ruin the single most expensive part of your bike (the frame.) If you allow the tire to keep rubbing the frame, it is going to ruin your tire and wear a hole in the frame.
Anyhow, it is a good thing there is no play in the wheel.
I wouldn't worry that the frame is flat where the skewer clamps. When the skewer is properly adjusted, it should hold nicely via pressure regardless of whether there is any knurling on the frame.
If the nut on the opposite side of the skewer clamp or the thead on the skewer is stripped you need to replace it. Don't mess around, just get a new one. Skewers, unless you go for a titanium, are quite inexpensive as far as parts go and all bike stores will have them in stock.
In the future you need to be sure your skewers are properly adjusted. With the quick release lever halfway open, you should tighten the nut until it makes contact with the fork. Then close the quick release lever. The lever should require firm, but not great, pressure to fully close. If it closes easily, release it, tighten the nut a bit more and try again. If it requires a lot of pressure to close, open the lever, loosen the nut a bit and try again.
You may want to review the Park Tool website for more information on adjusting your skewers and nearly all other types of repairs.

Hope this helps.
How do working capital (WC) and the quick ratio (QR) change when stock is purchased?
@qaa_question
If you buy stock for cash, working capital will stay the same becuase stock and cash both form part of working capital and the stock will go up by an amount equal to the cash spent.
If you buy on credit the double entry is debit stock and credit creditors. Once again working capital stays the same.
The Quick Ratio is current assets over current liabilities. This remains unchanged in the case of a cash purchase or credit purchase
