Axis Definition and 928 Threads

The Axis powers, originally called the Rome–Berlin Axis, was a military coalition that fought in World War II against the Allies. The Axis powers agreed on their opposition to the Allies, but did not completely coordinate their activity.
The Axis grew out of the diplomatic efforts of Nazi Germany, the Kingdom of Italy, and the Empire of Japan to secure their own specific expansionist interests in the mid-1930s. The first step was the protocol signed by Germany and Italy in October 1936. Benito Mussolini declared on 1 November 1936 that all other European countries would from then on rotate on the Rome–Berlin axis, thus creating the term "Axis". The almost simultaneous second step was the signing in November 1936 of the Anti-Comintern Pact, an anti-communist treaty between Germany and Japan. Italy joined the Pact in 1937 and Hungary and Spain joined in 1939. The "Rome–Berlin Axis" became a military alliance in 1939 under the so-called "Pact of Steel", with the Tripartite Pact of 1940 leading to the integration of the military aims of Germany, Italy and Japan. As such the Anti-Comintern Pact, the Tripartite Pact, and the Pact of Steel were the agreements that formed the main bases of the Axis.Particularly within Europe, the term "the Axis" is still often used primarily to refer to the alliance between Italy and Germany, though outside Europe it is normally understood as including Japan.At its zenith in 1942 during World War II, the Axis presided over territories that occupied large parts of Europe, North Africa, and East Asia. In contrast to the Allies, there were no three-way summit meetings and cooperation and coordination was minimal, and on occasion the interests of the major Axis powers were at variance with each other. The war ended in 1945 with the defeat of the Axis powers and the dissolution of their alliance. As in the case of the Allies, membership of the Axis was fluid, with some nations switching sides or changing their degree of military involvement over the course of the war.

    Find the length of the Transverse axis. What did I do wrong?

    I'm doing an Exam correction an I can't see how this answer is found. Question: x^2 - \frac{\ y^2}{9} = 1 Find the length of the transverse axis. I took x^2 - \frac{\ y^2}{9} = 1 And plugged it into \frac{\ (x-h)^2}{b^2} - \frac{\ (y-k)^2}{a^2} = 1 to get \frac{\ (x-0)^2}{1^2}...

    Can a wave rotate about its axis?

    Can a wave rotate about its axis?? Can a transverse wave "rotate" about its longitudial axis (kind of like an airplane's "roll" maneuver)? If it could, i don't think we could detect it; if it did, i don't think anything will really get affected. But could it?? Not that it would...i mean...

    General question about finding area of a solid by rotating axis

    I just have a general question here. There's this question in the textbook that asks to sketch a graph and then find the volume generated by revolving the region about the x-axis. The three equations they give is y = x, y = 0, x = 1. Aren't we suppose to sketch a graph of those three...

    What Causes Earth's Tilt on Its Axis?

    i was wondering what causes the Earth's tilt on its axis. i was thinking that it might be from einsteins theory of gravity, in which a large object, such as the sun, causes a bend in space time forming gravity and causing Earth to rotate around it. any info would be great, thanks

    Does Rolling Without Slipping Cause Wheel Deformation?

    I have some doubts on the following: When a wheel rolls without slipping, the point of contact of the wheel with the ground is instantaneously at rest. It is sometimes useful to think of the motion of the wheel as pure rotation about this "instantaneous axis". Points [on the wheel] close to...

    Rotational Freefall and Designation of Axis

    Well, I'm not even sure if freefall is the right word, but my first quandary is as followed: If two objects fall from the same height, and one object will begin to rotate after it has been release (ie. a yoyo), while the other will not rotate, then the rotating object will accelerate slower...

    How does the earth keep spinning on its axis?

    how does the Earth keep spining on its axis? is it because it still has the energy it gained when it was formed because it doesn't lose energy into space cause there's no particles out there, but then i was thinking does it loes any energy through IR radiation? just curious.

    What is the distribution of force in a rotating object without a fixed axis?

    The problem is this: a rigid object is in free-fall, and a force is applied so that it would be a torque if the object had a fixed axis through its center of mass. But the object doesn't have such an axis. How much of that force turns into linear motion, and how much of it goes into rotation...
