What one of the following does not have some dimensions?
Moment of inertia and torque
What is the constant of proportionality between torque and angular acceleration?
The rotating object's moment of inertia. Similar to Newton's Second Law, commonly quoted as "force = mass x acceleration", there is an equivalent law for rotational movement: "torque = moment of inertia x angular acceleration". The moment of inertia depends on the rotating object's mass and its exact shape - you can even have a different moment of inertia for the same shape, if the axis of rotation is changed. If you use SI units, and radians for angles (and therefore radians/second2 for angular acceleration), no further constants of proportionality are required.
Difference between torque and moment?
Torque is a movement force. Moment is a static force.Torque is often presented as Nm/revolution and moment is typically presented as Nm.The words "torque" and "moment" (of force) mean the same.However, "torque" tends to be used when there is an axle or pivot to be turned around, while "moment" tends to be used in essentially non-rotational situations, such as analysis of forces on a beam.
What is the difference between torque and couple?
The turning effect of a force is called torque or moment of the force. SI unit of torque is Newton-Metre. T = FL i.e Torque = Force x Moment arm A couple is formed by two unlike parallel forces of the same magnitude but not along the same line.
What is the use of moment of inertia?
moment of inertia is the rotational equivalent of mass. it is given by I= Mk2 moment of inertia in rotational motion play the same role as mass in linear motion, that is in linear motion f = ma while in rotation, torque= I*Angular acceleration where I is the moment of inertia
Can you find torque by time in moment of inertia?
Comparing linear and circular motion we can see that moment of inertia represents mass and torque represents force. So the product change in the circular momentum per unit time is torque. Circular momentum is the product of moment of inertia and circular velocity.

Moment of inertia and torque
Mass moment of inertia of a flywheel?
define moment of inertia§ I is the moment of inertia of the mass about the center of rotation. The moment of inertia is the measure of resistance to torque applied on a spinning object (i.e. the higher the moment of inertia, the slower it will spin after being applied a given force).
What is inertia torque?
Inertia torque an imaginary torque, which when applied upon a rigid body, brings it in an equilibrium position. Its magnitude is equal to accelerating couple, but opposite in direction.T1 = -IαwhereI = mass moment of inertia of body andα = angular acceleration

What is the equation of torqe?
The net torque is equal to moment of inertia times angular acceleration. (Στ=Ia)

Is angular acceleration proportional or inversely proportional to torque?
Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).

What is bending moment and torque and its difference?
Torque_vs_Couple">Torque_vs_Couple">Torque_vs_Couple">Torque vs Couple• The turning effect produced by a force on a body is called torque. It is calculatedas force multiplied by perpendicular distance.• A couple is a special case when there are two equal but opposite forces acting ona body that rotate it.
Is moment scalar or vector?
Is moment scalar or vector and why? Scalar has magnitude, but no direction. Vector has magitude and direction. Speed is a scalar. The car's speed is 25mi/hr. No direction is mentioned. Velocity is a vector. The car is traveling 25 mi/hr 20º North of East. Velocity is a vector, because it has magnitude and direction Moment has two meanings Moment of inertia = ∑ Mass* raidus^2 This moment measures how difficult it is to rotate an object. This moment is a scalar. Moment can also mean torque. Torque = Force x distance* sinθ (cross product). However torque can be clockwise or counter-clockwise. So torque is a vector.
