WebbA wheel of mass 1 0 k g and radius 2 0 c m is rotating at an angular speed of 1 0 0 rev/min when the motor is turned off. Neglecting the friction at the axis, calculate the force that must be applied tangentially to the wheel to bring it to rest in 1 0 revolutions.
Webb22 dec. 2024 · The MR 2 component is the moment of inertia for a point mass at a distance R from the axis of rotation, and the equation for a specific rigid body is built up as a sum of point masses, or by integrating an infinite … Webbat rotation curve to 4R0 without a dark halo. To be con dent about the dark halo, one needs to have the rotation curve for & 5R0. In practice, that means HI measurements: optical rotation curves do not go out far enough to say anything conclusive about dark haloes. The rest of this section is a more detailed working out of the previous paragraph.
WebbNow do the second term. The minus of the 0 term is just minus 0. So that just stays 0. Then you multiply 2 times the y term. So 2 times y is going to be equal to 2 times 1, so it's equal to 2. So now we can describe this transformation-- so now we could say the transformation of some vector, x, y. We can describe it as a matrix-vector product.
