are torque and moment the same?

In physics, they signify the same thing but in mechanics, they hold slightly different meanings. Both have the same unit i.e. N-m but torque is a movement force whereas the moment Is a static force. Torque is used where there is rotation involved whereas moment Is used where there is no rotation.

Moment is the perpendicular distance between the point of rotation and the force's line of action while torque is a measure of the turning force of an object. ... Moment is a static force while torque is a movement force. 6. Moment is used when there is no rotation while torque is used when there is rotation and a pivot.

The moment of inertia is a resistance to turning about an axis, just as inertia is resistance to movement. ... The second moment of area is a property of a shape that is used to predict the shapes resistance to bending and deflection which are directly proportional.

A dynamometer, or "dyno" for short, is a device for measuring force, moment of force (torque), or power. For example, the power produced by an engine, motor or other rotating prime mover can be calculated by simultaneously measuring torque and rotational speed (rpm).

With torque, you talk about force at a distance, and angular acceleration instead of linear acceleration. Force has units of Newtons, while torque, being the product of a force and a distance, has units of Newton ⋅ meters.

In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. Torsion is expressed in either the Pascal (Pa), an SI unit for newtons per square metre, or in pounds per square inch (psi) while torque is expressed in newton metres (N·m) or foot-pound force (ft·lbf).

Simply resistance of moment is called bending moment and no resistance it continues to deformed or bend to some extent called as deflection … Cheers:).

In Newtonian rotational physics angular acceleration is inversely proportional to the moment of inertia of a body. You can think of the moment of inertia as the ability to resist a twisting force or torque. The angular momentum of a solid object is just Iω where ω is the angular velocity in radians per second.

Mathematically, torque can be written as T = F * r * sin(theta), and it has units of Newton-meters. When the sum of all torques acting on an object equals zero, it is in rotational equilibrium.

The magnitude of the torque with respect to a given axis of rotation can be approached as the force times the lever arm with respect to that axis. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. The direction of the torque is given by the right hand rule.

In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity—the total angular momentum of a closed system remains constant.

What are the relationships between speed, torque, wheel size, and RPMs? There are several. Generally speed and torque are opposed to each other. With a small gear (More speed, less torque) turning a larger gear (less speed, more torque) you sacrifice speed to gain the torque.

In general, on a DC motor, speed is proportional to voltage and torque is proportional to current. As your load increases and you need more torque, the motor will draw more current. If you need to speed your motor up or slow it down, you need to raise or lower your voltage.

Speed: The speed of a motor, at its most basic form, is the rate at which the motor spins. The speed of an electric motor is measured in rotations per minute, or RPM. Torque: The torque output of a motor, at its most basic form, is the amount of rotating force the motor develops.

As you can clearly see Torque is maximum at mid rpm's whereas Power is maximum at the top of the rev band. This is because max Torque occurs at the maximum Volumetric Efficiency of the engine. Volumetric efficiency is the breathing ability of the engine or how efficiently your engine breathes (sucks in air).

The basic difference being is that mass moment of inertia is concerned with rotating body whereas area moment of inertia concerned with the bending stresses developed in the body.

Torque is the rotational equivalence of linear force. Power is work done in a time interval. The relation between Torque and Power are directly proportional to each other. The power of a rotating object can be mathematically written as the scalar product of torque and Angular velocity.
