    Slider crank mechanism mass moment of inertia

    But I want the moment of inertia about z. So the constraints in motion play a part. for example when theta is zero the block mass is not moving much with respect to theta. At 90 degrees the block is moving a lot with respect to theta. I may have not been clear but the inertia is changing...

    Slider crank mechanism mass moment of inertia

    I need help solving a mass moment of inertia for a slider crank mechanism. I've done my best to sketch it in the attachment. This will be used for sizing of a motor. Homework Statement Link A has mass Ma and is located Acg distance from its pivot point Z Link B has mass Mb and is located Bcg...

    What is the Flow Rate of Water Through a Square Tube?

    I have been trying to use this but the dimensions do not cancel out at the end. using SI units: for \rho I have \frac{kg}{m^3} for \Delta P I have \frac{N}{m^2}=\frac{kg m}{m^2}=\frac{kg}{m} for a^3 I have m^3 for L I have m for \mu^2 I have Poise^2 = Pa^2 s^2 = \frac{N^2 s^2}{m^4}=...

    What is the Flow Rate of Water Through a Square Tube?

    Actually this is not homework. I am a mechanical engineer designing irrigation products. And yes my pressures are gauge pressures. Thanks for your help. I am excited to see you run through the solution.

    Are Orthogonal Matrices Compact?

    How can you prove that the set of orthogonal matrices are compact? I know why they are bounded but do not know why they are closed.

    Proofs in Linear Algebra: Countable Sets, Algebraic Numbers, and Fields

    Linear Algebra proof I would appreciate any help with any of the foolowing: 1. Let C be a countable set. Prove that any linear well-ordered on C with the property that whatever c in C there are only finitely elements c` with c`<c, is unduced from the canonical order on N via a bijection N->...

    Solving Difficult Wave Function Problems

    i am having difficulty with the wave function. for example in the exercise we are told to write the expression : a cos x+ b sin x in the form k cos(x-a) This i had little problem with and was able to work out what quadrant i shoul use etc what i mean is the all positive. sin positive...
