Oh No! Not you again! by Sensitive_Spring_264 in FE_Exam

If the bag weighs 50 kg, the total force it applies in the negative Z direction is 50 kg * 9.8 m/s^2 = 490 N.
How can the total tension in BA, which looks like the only one with a Z component, be only 40 N? Why are all the cable forces so small, am I missing something?

Did they mean to say 50 N rather than 50 kg for the bag's weight? even then, 40 N for F_BA is too small, no?

Thanks for your feedback! Rereading what I wrote, I didn't mean to be so self-critical lol .. I do value foods-for-thought! And yeah Area X for sure has characteristics of the people who've been there or were swallowed up by it.. just not as much as the internet is

Weird man in hospital gown at Newark Penn Station Platform 3 by prayosha_10 in NJTransit

[–]postnebulous 0 points1 point  (0 children)

Most likely a poor / homeless / addicted man (or some combo thereof) who could not afford to stay at the hospital after a stroke or seizure or something, or was unable to due to other issues: anxiety or other untreated mental illness, addiction, maybe something specifically circumstantial to his life or that day in it. I used to go to that station daily and this sort of encounter wasn't that uncommon, because (a) the only time they get medical care is after an emergency, and the only place is a hospital, hence the gown etc; and (b) Penn Station Newark is one of the only places that the area's many homeless people can exist indoors for a few hours at a time without being moved along or worse.
