• The turning effect produced by a force on a body is called torque. It is calculated
as force multiplied by perpendicular distance.
• A couple is a special case when there are two equal but opposite forces acting on
a body that rotate it.

∙ 13y agoThe terminology is, unfortunately, somewhat confusing; what I learned to call "torque" in a U.S. physics high-school book - a product of force x distance - is called "moment" in some other countries. Then there is the "moment of inertia", which is really rotational inertia, and a quite different concept. The Wikipedia article on "Torque" explains the differences interminology in more detail.

∙ 11y agoThe difference corresponds with one's nontechnical intuition about the difference between bend and twist.
Just as a bend deformation is different than a twist deformation, the labelling of the force times distance (moment) is different.
For twisting, cross-sections normal to the moment vector rotate with respect to each other in plane.
For bending, the cross-sections normal to the moment vector do not rotate with respect to each other.
A picture would be helpful. Some information is in related links.

∙ 14y agoTorsion is twist. Hold a rod in your hands and turn one hand clockwise and the other counter-clockwise. That is torsion.
Moment is bending. Stand on the end of a diving board. That is a moment.

What do you mean bu equivalent shear force and equivalent bending moment?
MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment
Why you study about shear force and bending moment?
The importance of shear force and bending moment diagram in mechanics lies in structural design and in deflection of beams.
Why is the maximum bending moment of a structural member as the point of zero shear?
Shear is the rate at which bending moment changes or shear is its derivative with respect to span. The integral, bending moment, goes through a maximum when shear goes from positive to negative or vice-versa.
What is the difference between Bending STRESS and Direct Stress?
direct stress is a stress normal to the cross section, A, and is the result of an axial load, P. direct stress = P/A Bending stress also acts normal to the cross section but varies from tension on one side and compression on the other. and is the result of a bending moment, M. bending stress = Mc/I where I is the area moment of inertia and c the distance from outer fiber to neutral axis
Where does point of contraflexure occurs?
it occur where moment becomes zero in bending moment diagram.
What is difference between moment and bending moment?
Take a beam as an example. Moment is responsible for a beam to rotate about some axis. Whereas bending moment are a pair of moments which will not rotate the beam but it will deflect it.
What is the difference between deflection and bending?
Bending moment With "bending" you really mean the bending moment. The bending moment in an inner stress within a member (usually beam) that allows it to carry a load. The bending moment doesn't say anything about how much a beam would actually bend (deflect). Deflection Deflection measures the actual change in a material you could call "bending." It measures the physical displacement of a member under a load.
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.
Why point moment jumps bending moment in the beam?
moment
What do you mean bu equivalent shear force and equivalent bending moment?
MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment
What is the difference between mass moment of inertia and area moment of inertia?
mass moment of inertia is the property of the body to resist rotation about the given axis where as the area moment of inertia is the resistance to bending about the given axis
What is the difference between bending moment and deflection?
monment is force by distance however the deflection is a displacement of point measured by distance
What will be the shear force when bending moment is constant?
On SFD's and BMD's: The shear force will be 0, the shear force is the derivative of the bending moment at a point on shear force and bending moment diagrams. Otherwise: It depends on the loading.
What is bending moment?
bending force is the amount of energy it takes to compromise the item from its natural shape or conditionA bending force is a combination of tension and compression.
What is a bending moment in applied mechanics?
Its
What is mean by bending moment?
when a moment is applied in a structure the element bend
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.
