$A$ body of mass $2 \ kg$ is suspended as shown in the figure. The tension $T_1$ (in $kg-wt$) in the horizontal string is :-

Define mechanical advantage in a lever.

Which of the following sets of three forces acting on a body cannot have a resultant of zero?

$A$ mass $M$ is suspended by a rope from a rigid support at $A$ as shown in the figure. Another rope is tied at point $B$,and it is pulled horizontally with a force $F$. If the string $AB$ makes an angle $\theta$ with the vertical in equilibrium,then the tension in the string $AB$ is:

$A$ rope of mass $5 \,kg$ is hanging between two supports as shown. The tension at the lowest point of the rope is close to ........... $N$ (take $g=10 \,m/s^2$).

Three concurrent co-planar forces $1 \,N$,$2 \,N$,and $3 \,N$ acting along different directions on a body:
