    Pumping fluid against a centrifugal force

    Hello. I am in need of some assistance regarding a theoratical problem I have. It goes something like this: Imagine a vertically placed axle, rotating at a constant angular velocity (omega). From the middle of this axle extends an arm and on the edge of that arm is a unit containing...

    Solving 2D Pulley Forces Problem with Force F and Angle theta

    Initially, when the angle theta = 0, then the force F is obviously divided equally between S1 and S2, but as the angle theta becomes > 0 and the mass m has displaced from it's original position, I would assume that F divides differently between the two S Forces. It is this division of F after...

    Solving 2D Pulley Forces Problem with Force F and Angle theta

    Hi Doc. A diagram is here: http://picasaweb.google.com/helgi2000/Iceland2008/photo#5201292838334570434 And yes, the pulley can be considered massless and frictionfree. (P.S. I had to put spaces in the URL 'cause I'm new at the forum and they won't allow me to post URL's yet) Thank you. H.

    Solving 2D Pulley Forces Problem with Force F and Angle theta

    Homework Statement The problem is a 2D one, regarded as seen from above (no gravitational forces are relevant). A pulley is attached to a cable and is pulled with the force "F" towards north. Through the pulley goes another cable and is firmly attached to the ground on one end and attached to...
