Let’s talk about nobody’s favorite physics concept: torque. Torque is pretty magical, honestly, and if you’re not already familiar with it then you absolutely should be. Chances are you’ve applied the principle of torque hundreds, if not thousands, of times in your life. You may have even done it today, without even thinking about it.

What is torque? Put simply, it’s force applied in a circle. Mathematically it’s the vector cross-product between a force applied in a particular direction and a radial level arm, but who cares about the math. What we care about is what torque does. The greater the force applied, the greater the torque. But the longer the lever arm, also the greater the torque. And the more torque you have the more cool things you can do.

Try to open a door near the handle (you know, like doors are designed to do). Pretty simple. Try opening the door near the hinges. Quite a bit harder, isn’t it? You’re applying the exact same force, but your lever (the distance away from the point of rotation) is shorter. Your torque is weaker.

Can’t get that bolt unstuck with your hands? A wrench makes the lever longer, increasing the torque, making the bolt come unstuck.

Like I said, torque is magic.

Forces causes acceleration in a straight line. Torque causes acceleration in a circle, otherwise known as spinning. Your kids climb on top of one of those spinning merry-go-round contraptions at the playground, and what do you do? You push it. You apply a force, and there’s a lever between your force and the center of rotation. You’re applying a torque. That torque sets the contraption in motion. Your kids squeal with delight and possibly vomit.

As with all physics concepts, especially the magical ones, torque is universal, and we can see its application across the cosmos. The most common example is very similar to the case of you spinning your kids into vomitdom at the playground, except that instead of the creaky metal contraption you have a star, and instead of your hands you have…another star.

Stars often come in binary systems, and because random chance is random chance, one star will just happen to have more mass than the other. And the larger the star, the faster it burns through its fuel supply, and the sooner it dies. But before stars finally extinguish their light, they have a tendency to get really, really big.

And when they do, the atmosphere of one can spill onto the other. Since those stars are already in orbit around each other, that falling gas swirls around and around before impacting the partner star. So at the moment of collision, that gas isn’t just falling in directly like a fist to the stellar gut, but at an angle.

An angle, like a hand at a carousel.

The falling gas applies a force. It’s applied some distance away from the axis of rotation of that star. A torque is applied. The star accelerations. It spins, faster.

The most extreme examples of this occur in the form of magnetars, dead embers of once-great stars. Imagine for a moment an object more massive than the sun spinning faster than a kitchen blender.

Yeah, torque is magical.

Let’s discuss no one’s preferred physics principle: torque. Torque is quite wonderful, truthfully, and if you’re not currently knowledgeable about it then you definitely need to be. Opportunities are you have actually used the concept of torque hundreds, if not thousands, of times in your life. You might have even done it today, without even thinking of it.

What is torque? Simply put, it’s force used in a circle. Mathematically it’s the vector cross-product in between a force used in a specific instructions and a radial level arm, however who appreciates the mathematics. What we appreciate is what torque does. The higher the force used, the higher the torque. However the longer the lever arm, likewise the higher the torque. And the more torque you have the more cool things you can do.

Attempt to open a door near the manage (you understand, like doors are developed to do). Pretty easy. Attempt unlocking near the hinges. A fair bit harder, isn’t it? You’re using the precise very same force, however your lever (the range far from the point of rotation) is much shorter. Your torque is weaker.

(************ )Can’t get that bolt unstuck with your hands? A wrench makes the lever longer, increasing the torque, making the bolt come unstuck.

Like I stated, torque is magic.

Forces triggers velocity in a straight line. Torque triggers velocity in a circle, otherwise called spinning. Your kids get on top of among those spinning merry-go-round devices at the play area, and what do you do? You press it. You use a force, and there’s a lever in between your force and the center of rotation. You’re using a torque. That torque sets the device in movement. Your kids screech with pleasure and potentially throw up.

Just like all physics ideas, particularly the wonderful ones, torque is universal, and we can see its application throughout the universes. The most typical example is extremely comparable to the case of you spinning your kids into vomitdom at the play area, other than that rather of the creaky metal device you have a star, and rather of your hands you have … another star.

Stars frequently can be found in double stars, and since random opportunity is random opportunity, one star will simply occur to have more mass than the other. And the bigger the star, the quicker it burns through its fuel supply, and the quicker it passes away. However prior to stars lastly extinguish their light, they tend to get truly, truly huge.

And when they do, the environment of one can spill onto the other. Because those stars are currently in orbit around each other, that falling gas swirls around and around prior to affecting the partner star. So at the minute of accident, that gas isn’t simply falling in straight like a fist to the outstanding gut, however at an angle.

An angle, like a hand at a carousel.

The falling gas uses a force. It’s used some range far from the axis of rotation of that star. A torque is used. The star velocities. It spins, quicker.

The most severe examples of this take place in the kind of magnetars, dead ashes of once-great stars. Think of for a minute a things more enormous than the sun spinning faster than a kitchen area mixer.

Yeah, torque is wonderful.
