It is an interesting exercise; I can draw up the free-body diagram pretty easily, but I’m going to have to dust off some math I haven’t used in two decades to actually grok out some actual values. (And I really wanted to ride my bike this morning, than do homework)
Anyhow, I stand by the assertion that the OP claims of “we stored our bikes on hooks when we were kids and it damaged the wheels” is probably more due to poor practices (no offense intended) like hanging against the spokes, or twisting the bike to get it on or off of the hook; also could be inexpensive bikes with lower quality wheels (which are demonstrably more easily damaged) rather than “Hooks Damage Wheels”
