And 20 kg is 44 lbs…I don’t think it’s all THAT significant…
why are you getting all girly snippy?
at least the guy asked the question.
This is why folks don’t want to ask questions, some guys get their panties in a wad.[/quote]
Haha it was meant in jest, jeez! Is everyone’s sarcasm detector broken?

oh my bad then. It seems like everyone else got your sarcasm but me! Sorry I girlied out on your humor.

most steel (what bars are made out of) can be made harder by the addition of alloying elements or heat treatment. This would not change the density of the bar (or the resulting weight) but would make them stronger / more ductile and better suited for higher weight.
I’ve got mixed feelings about the spirit of this thread. On the one hand I don’t like the inference that any question is ‘stupid’ or that anyone who asks one ought to feel sheepish. On the other, I applaud, loudly, the effort to remove any long-standing, festering areas of ignorance.
I’ve been lifting on and off for 20 years, and only recently found out that calories are sub-sub properties of food, in the way that protein, carbs and fats are sub-properties, where before I thought cals were on the same level, a fourth sub-property. I recently found that out here, and I’m PROUD I added 50Ibs of lean muscle never even knowing this basic nutritional fact.
Anywyay, do I have a question I think will get only stupid, or more likely zero replies? Yep.
What’s the name and address of a Physio/Chiro in NW London with extensive experience in fixing shoulder injuries?

Have you asked BushidoBadBoy about the chiro? I think he was or is a chiro student so he may have some good suggestions for you.
How much weight can a standard 45lb bar withstand on one side with the other side being empty before it tips over? This is a question more related to physics than bb, but I’m curious, nonetheless. I believe the most I’ve ever had on one side, while the other side was empty, was 2 45lb plates. Who dares to go higher?

I’m pretty sure I’ve had two 45’s and a 25, but the bar was pushed as far right as it could on the rack, which probably saved it from tipping over. I definitely probably wouldn’t do it again, let alone anything higher.
And responding the the first question, I’ve always counted the bar when lifting. I was always taught to, seems wierd not to.

depends on the width of the rack, I went to a gym with a narrow rack and 2 20kg plates on one side was enough for it to start to tip.

Haha, my buddy and I were actually discussing this, I’ve found it depends more on the rack.

haha that’s something i always wondered too…the most i go is having 2 45’s on each side

Here’s a stupid question:
If emotional states can effect T-levels, then if you lift while pissed off or horny, would that be more anabolic?

Bingo.
The physics are pretty simple: an uneven load on one side or the bar is going to create a torque about the axis of the nearer J-hook. The bar will tip (that is, rotate about that axis) when that torque is greater than the torque exerted by the mass of the (empty) part of the bar on the other side of the J-hook.
Basically, the closer the support is to the loaded side, the larger load it will take to tip the bar.
This will also depend on the weight of the bar (it will take a larger load to tip a heavier bar), and the elasticity of the bar (more elastic means greater load because some of the energy will be spent deforming the bar).
