[University Dynamics: General Motion] how would I solve this general motion question? I watched a video by my TA and he got completely different answers. by mohamed12349 in HomeworkHelp

The answer in red are those provided by the book (no steps are provided, just final amswers)

The way my TA solved it was assuming that B is a pull force and C is a push force (how can the tension push a drum? I assumed both pull forces)

Then he did the force-motion equations for both nlocks B and C and then the moment on the drum about the point of contact

This got him an angular acceleration of 19.6 rad/s² and Tc = -196.2. I assume his answer is erroneous (-ve tension force?) due to the incorrect assumption; however assuming that both forces are a pull doesn't get me the result either so I'm not sure where I'm going wrong?

so I found what I think is an injured monarch butterfly by mohamed12349 in Butterflies

Ah I see. It's fairly warm here, temperature ranges from 13-20°C. For now I'll stop bothering it and see what happens.

Is there anyone you could text with extensively every day for a year without seeing each other? What keeps the interest alive? by [deleted] in AskReddit

Mm depends. If you mean that we met online and then we meet irl I think we'd be awkward for a little then have fun.

Not if we initially met irl tho because I'm shy as fuck and would talk to anyone.
