$A$ $100 \ N$ weight is suspended in a corner of a room by two cords $A$ and $B$ as shown in the figure. The tension in the horizontal cord $A$ is ............ $N$.

One end of a horizontal uniform beam of weight $W$ and length $L$ is hinged on a vertical wall at point $O$ and its other end is supported by a light inextensible rope. The other end of the rope is fixed at point $Q$,at a height $L$ above the hinge at point $O$. $A$ block of weight $\alpha W$ is attached at the point $P$ of the beam,as shown in the figure. The rope can sustain a maximum tension of $(2 \sqrt{2}) W$. Which of the following statement$(s)$ is(are) correct?

Explain the main types of forces with suitable examples.

Which of the following groups of forces could be in equilibrium?

Four forces are acting at a point $P$ in equilibrium as shown in the figure. The ratio of force $F_{1}$ to $F_{2}$ is $1: x$,where $x = ....$

Can a stationary object remain stationary if multiple external forces act upon it?
