If you’re given the components of a vector, such as (3, 4), you can convert it easily to the magnitude/angle way of expressing vectors using trigonometry. For example, take a look at the vector in the image. Suppose that you’re given the coordinates of the end of the vector . Chapter 21 Vectors: The Cross Product & Torque 21 Vectors: The Cross Product & Torque. Do not use your left hand when applying either the right-hand rule for the cross product of two vectors (discussed in this chapter) or the right-hand rule for “something curly something straight” discussed in . The torque is defined as the cross product between the force vector and the displacement vector from the center of the object to the point where the force is applied: $\vec{\tau}=\vec{r}\times\vec{F}$. The direction of the vectors is important when calculating cross products. Notice if the direction is reversed in the displacement vector.

# Direction of the torque vector

Torque is defined as = r x F = r F sin(). In other words, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, 'a' being the angle between r and F.. Using the right hand rule, we can find the direction of the torque UpsidedownSchoolroom.com we put our fingers in the direction of r, and curl them to the direction. The cross product and the direction of torque If you're seeing this message, it means we're having trouble loading external resources on our website.

Do not use your left hand when applying either the right-hand rule for the cross product of two vectors (discussed in this chapter) or the right-hand rule for “something curly something straight” discussed in . Jul 27,  · Direction of Torque. #1. UpsidedownSchoolroom.comy. Hi, Let us assume that I apply some amount of force at the end of the wrench to loosen a nut. This force makes the wrench to rotate in clockwise direction. So the direction of the torque should also be in clockwise direction. Sep 17,  · Answers. By definition, the torque is applied in the direction of the bolt's axis. So it's either going to be a torque pointing to the butt of the bolt or to the tip of the bolt. You have to use the Right-Hand-Rule to tell which direction the torque is in. If you are loosening the bolt, turning the wrench counter-clockwise, Status: Open.Torque is a measure of how much a force acting on an object causes that object to Using the right hand rule, we can find the direction of the torque vector. The direction of the torque vector is only significant once an arbitrary convention ( i.e. the right hand rule) has been chosen. Really I think it. Angular motion has direction associated with it and is inherently a vector Newton's 2nd law for rotation implies that the torque is also in the axis direction. Torque. Torque is the rotational equivalent of force. To get an object to move in a Using your right hand, point your fingers in the direction of the first vector (r). Only unintuitive thing is to memorize which direction of the torque vector represents rotation to.
