How effective is torque?
In physics and mechanics, torque is the rotational analogue of linear force. It is also referred to as the moment of force (also abbreviated to moment). The symbol for torque is typically , the lowercase Greek letter tau. When being referred to as moment of force, it is commonly denoted by M.

- What is the difference between torque and moment?Torque is a special case of moment, such that it relates to the axis of the rotation driving the rotation, whereas moment relates to being driven b...
- Is torque energy?No, torque is not energy.
- How does torque differ from force?Torque is a counterpart of force in rotational mechanics. The basic difference between them is that torque is the ability of a force to produce a t...
- What is the difference between torque in an electric medium and torque in a magnetic medium?Torque is defined as the product of force and the perpendicular distance between the point of application of force and the pivot point. Torque in a...
- What are some examples of torque in everyday life?Opening a bottle cap or turning a steering wheel are examples of torque.
Learn how to find the torque exerted by a force on an object that can rotate about an axis. Explore the concepts of static and dynamic torque, rotational equilibrium, power and energy, and torque in rotational kinematics.
- In the middle of the article, it says P = (F * 2pi* r)/t. F*r is torque. So P = ((torque)*2pi)/t. Th...My first reply was just wrong, and here is the correction: You are correct that F*r = torque, and that angular velocity is rad/sec. To see why P =...
- Isnt a Newton-meter a joule?The units for torque (Newton-meter) and energy (Joules) are dimensionally the same, but torque and energy are not equivalent. The difference is tha...
- I didn't understand how we solved exercise 2b, can someone please explain it in a better way?The formula for finding the (tangential) velocity is v=rω This comes from taking the derivative of both sides of s=rθ (where s is arc length) with...
- In 2a, can anyone explain how tau(w)=tau(m)/r? R is only the factor by which speed reduces right? Ho...Power= τ*ω P of winch drum= τ(of winch drum)*ω(of winch drum); or in other words: P_w=τ_w *ω_w where that w stands for winch drum The power remains...
- Can we solve this problem using law of conservation of momentum?No, I suppose momentum will not remain conserved because a constant force is acting on the system. which will lead to acceleration and thus velocit...

Nov 25, 2023 · Torque is the measure of how much a force acting on an object causes that object to rotate, creating a tendency for the object to rotate about an axis, fulcrum, or pivot. Torque is most commonly classified as "twist", rotational force, or angular force to an object and applying it to a system changes the angular momentum of the system. The ...
