    Undergrad Partial fractions - having 1 in the numerator?

    This is probably a "basic" question, but I can't seem to remember how to do partial fractions problems where there is only a 1 in the numerator. For example (just making this up), let's say I have: 1/s(s+4)(s+5) So what I'd do is 1/s(s+4)(s+5) = A/s + B/(s+4) + C/(s+5) as one would expect...

    Help with a dynamics homework problem

    Well, I think you should be able to figure it out. If I did the math correctly, the first, straight section is 0.5 m (given), and by way of the pyth. thm., the second section should be ~1.12 m

    Help with a dynamics homework problem

    here's what I'm thinking (feedback please on my thinking). Part A is self-explanatory and can be found using that simple equation in post #2 by kataya. Then, the part C can be found by finding the acceleration at point B (using given info, should be doable by alpha*r on member AB), then it's...

    Help with a dynamics homework problem

    I have a question furthering this: for part B, which omega is the appropriate one for the equation? Is it the omega of member CD or member BC? Can we assume that for *this instant*, member BC is only in translation (hasn't started rotating yet since its still perpendicular to member AB), and...
