Any translation can be replaced by two reflections. Any translation can be replaced by two reflections. Show that if a plane mirror is rotated an angle ? The fundamental difference between translation and rotation is that the former (when we speak of translation of a whole system) affects all the vectors in the same way, while a rotation affects each base-vector in a different way. When we translate the line 3 units to the right, its slope will remain the same, but its x-intercept will now be 3.

In other words, the rolling motion of a rigid body can be described as a translation of the center of mass (with kinetic energy Kcm) plus a rotation about the center of mass (with kinetic energy Krot). If you draw a circle around the origin, and then reflect a point in two straight lines at an angle $\theta$, the point rotates $2\theta$. We speak of $R$ is rotor of angle $\theta$ if $m\cdot n=\cos\frac\theta2$. In continuum mechanics, a rigid body is a continuous body that has no internal degrees of freedom. Copyright 2021 Dhaka Tuition. b. Does the order of rotation matter? Does it matter if you translate or dilate first? Rotating things by 120 deg will produce three images, not six.

It is easy to show by simply multiplying the matrices that the concatenation of two rotations yields a rotation and that the concatenation of two translations yields a translation. Scaling. Rotation: Any 2D rotation transformation is uniquely defined by specifying a centre of rotation and amount of angular rotation, but these two parameters don't uniquely define a rotation in 3D space because an object can rotate along different circular paths centring a given rotation centre and thus forming different planes of rotation. Remember that, by convention, the angles are read in a counterclockwise direction. The same rotations in a different order will give a different result. My preceptor asked .

It should be clear that this agrees with our previous definition, when $m = m' = 0$. In notation: $(k,1)\ast(k',m') = (k - k'\text{ (mod }n),1+m'\text{ (mod }2))$. (You'll have to take my word for now $\ast$ is associative-you can try to prove it, but it's a bit arduous). A non-identity rotation leaves only one point fixed-the center of rotation. Expert Answer The combination of a line reflection in the y-axis, followed by a line reflection in the x-axis, can be renamed as a single transformation of a rotation of 180 (in the origin). x Can a combination of a translation and a reflection always be replaced with one transformation? Since every rotation in n dimensions is a composition of plane rotations about an n-2 dimensional axis, therefore any rotation in dimension n is a composition of a sequence of reflections through various hyperplanes (each of dimension n-1).
