    Volume by rotating the y axis

    Hi, here is my problem: Find the volume formed by rotating the region enclosed by: and with about the -axis. So I get: V=\ 2\pi\int_0^{\sqrt6} (y^3)^2-(6y)^2 dy But my answer isn't right. Is this the correct way to set it up? Thanks, Matt

    Symmetric to which axis?

    The graph of y=cube root of (x^2+1) is symmetric with respect to which of the following? I. The X-axis II. The Y-axis III. The origin Now the multiple choice answers are combinations of these numbers, but I do have to show my work. Could someone clear this up without the use of a graphing...

    3 axis accelerometer forces as angles/vectors

    Hello, I have a three axis accelerometer that I am using in project that I am working on and I need to find the angle/vector of the axis’s when the device is not orientated to its designated axis, and when it is accelerating. If I lay the device flat on a horizontal surface and read the outputs...

    z axis.

    Hi everyone! So I have to do this problem for homework. However, my book doesn't show us how to draw a graph that involves a z-axis as well as an x and y-axis. It assumes that you know how, and I haven't done this before so I would appreciate any help.

    Application of Parallel Axis Theorem

    I am a civil engineer and have been in the field for 10 years so I have forgotten some basic theories of Maths. For me, what I remember is // axis theorem is able to make second moment of area of a section with reference with respect to any axis. In the basic bending theory of beam, the...

    Rotation around an axis

    Hello, I have made this "code" to rotate a point about another point, which stays at it's own place (notice that this is programmed, so: Math.sqrt is the square root, Math.sin is sinus etc.) : But this doesn't work properly: The point DOES rotate, and in a good circle with a radius equal...

    axis of pulley?

    I am stuck on a simple question that I belive could be a trick. it says - A 50kg body hangs at rest from a rope wrapped around a pully 15cm in diameter. what is the torque about the axis? the formula I have used for a similar question is Torque = Force x distance Force= Mass x Acceleration...
