Ok, with your help i feel confident about these problems. I have just figured out the horizontal beam one: Three equations, leaving sin theta in assuming there is an angle in the cable and not vertical: 1. R_(x) - T cos \theta = 0 2. R_(y) + T sin \theta - (\mbox{weight of...

Ok i believe i am understanding some of this a bit better. My progress so far: deltaTHETA = Wit + 1/2at^2 - angular displacement w = Wi + at - rotation rate (sorry i do not know how to insert nice looking formulas) Vt = rw - tangetiel velocity Using above V - alpha = V^2tan/r -...

Hi, i am glad i have found this site. I am taking an online physics course, the kind where you read the book, work the problems, and take the test. Needless to say it has been very hard on me. I must be really dense at physics because i have purchased supplemental books but to no avail. I have...
