> One of the principal ideas behind structural design is to distribute the load so that a ceiling or roof doesn't collapse. There is still weight acting on that beam, and we have 'engineering disasters' all the time in which a load bearing wall is insufficient to the task, and something collapses.
> Typically, supporting a weight is less difficult than lifting it because less stress is placed on smaller stabilization muscles and more of the load is supported by skeletal structure, but there's still a huge strength component to it.

You can not just go under a bar and support 500 pounds on your shoulders unless you have the strength to do so. You don't have to squat it but try to unrack it and just hold it up I bet unless you are strong enough you would crumble under that much weight. Trust me you need just as much strength to support something as you do to lift it. If yu can't support it you can't lift it. If anyone here thinks supportsing weight is easy get to a gym and throw a bunch of weight on and let me know how severe your injuries are cause you werent strong enough to support the weight you tried holding up.
