SI unit of moment of couple is _________
Couple is defined as the action of parallel equal and opposite forces acting about two different axis. Couple has the same SI unit as that of torque.
SI unit of couple is $$N \ m$$.
A slob is subjected to two force $$\overset{\rightarrow}{F_1}$$ and $$\overset{\rightarrow}{F_2}$$ of same magnitude $$F$$ as shown in the figure .Force $$\overset{\rightarrow}{F_2}$$ is in $$XY-$$ plane while force $$\overset{\rightarrow}{F_1}$$ acts along $$z-$$axis at the point $$(2\overset{\rightarrow}{i}+3\overset{\rightarrow}{j})$$. The moment of these forces about point O will be :
A uniform disc is acted by two equal forces of magnitude F. One of them, acts tangentially to the disc, while other one is acting at the central point of the disc. The friction between disc surface and ground surface is nF. If r be the radius of the disc, then the value of n would be? (in N)
The dimensions of torque are same as that of
Given $$\vec {F}$$ = (4$$\hat {i}$$ -10$$\hat {j}$$) and $$\vec {r}$$= (5$$\hat {i}$$-3$$\hat {j}$$). Then torque $$\tau$$ is
Moment of force= _____ $$ \times $$ distance of force from the point of turning.
