Question

what is the difference between moment and work?plz help

Answer 1

Work Is Force applied multiplied by Distance moved in the direction of applied force.

Moment is Force applied multiplied by perpendicular distance from the pivot.

both are N/m

Answer 2

so the only difference is that distance in work is moved in the direction of force WHILE moment isthe distance is perpendicular to the pivot???

Answer 3

@hashsam it should read:
both are N∙m

Usually work is in J, whereas moment stays in N∙m, but both units are homogeneous.

Answer 4

so in a exam how do you know if the question is taking about moment or work?

Answer 5

whenever they talk about levers or weights hanging from a rod, and you see the the force applied is perpendicular to the distance from pivot, and causes a CIRCULAR motion, clockwise and anticlockwise, then the question is talking about moment or torque.

With that said, force perpendicular means that the object is moving in a circular motion. while for work the force is in direction of distance so the object is moving forwards or backwards..

Answer 6

yeah N*M

Answer 7

wow!thnx guys,that helped a lot.god bless
