    Can a Lever Class Change During Rotation?

    Is it possible for a lever to change from one class to another during its rotation (e.g. it starts out as a third class lever and ends as a first class lever)?

    Calculating Force of Tension in Wire Rope: Bill O'Donnell

    Thanks for the responses Gentlemen: Although I still don't have a mathematical formula to use for calculating the tension in a cable, I have figured out the flaw in my thinking. At least I know the forces now. Thanks, again.

    Calculating Force of Tension in Wire Rope: Bill O'Donnell

    Hydraulic force Sir: I was asked how two hydraulic cylinders can pull a cable in opposite directions with unequal forces, so I answered the question. I presumed, since the questioner asked the question, that he did not know the answer. It was not my intention to imply that others don't...

    Calculating Force of Tension in Wire Rope: Bill O'Donnell

    Hydraulic cylinder forces Let's presume the annular piston areas of the two cylinders are equal to each other (say, 1 square inch). Let's presume, as well, that each cylinder is powered by an independent pump (and prime mover). The pressure relief valve of one pump is set at 100 psi and the...

    Calculating Force of Tension in Wire Rope: Bill O'Donnell

    I'm just trying to find out how to do the calculation No, Sir, I'm not making the problem harder than it needs to be. If you know how to calculate the tension in the cable, I'll be grateful if you will show me how to do it.

    Calculating Force of Tension in Wire Rope: Bill O'Donnell

    A wire rope is stretched horizontally between two opposing hydraulic cylinders. One cylinder pulls to the left with a force of 100 pounds, the opposing cylinder pulls to the right with a force of 150 pounds. What is the force imparted to the wire rope? Please show me how this is calculated...
