net torque $=0$

 about $c$

$\mathrm{Mg}\left(\frac{\ell}{2}ight) \sin \alpha-\mathrm{F}\left(\frac{3 \ell}{2}ight)=0$    $...(i)$

${\left(F_{	ext {net }}ight)_{y}=0}$               $...(ii)$

${F+N-M g \sin \alpha=0}$         

$\left(F_{	ext {net }}ight)_{x} =0$

$f_{\max } =M g \cos \alpha=0 $           $...(iii)$

$f_{\max }=\mu N$          $...(iv)$

A uniform rod $AB$ of weight $100\, N$ rests on a rough peg at $C$ and $a$ force $F$ acts at $A$ as shown in figure. If $BC = CM$ and tana $= 4/3$. The minimum coefficient of friction at $C$ is

$A$ horizontal force $F = mg/3$ is applied on the upper surface of a uniform cube of mass $‘m’$ and side $‘a’$ which is resting on a rough horizontal surface having $\mu_S = 1/2$. The distance between lines of action of $‘mg’$ and normal reaction $‘N’$ is :

Two uniform rods of equal length but different masses are rigidly joined to form an $L$ -shaped body, which is then pivoted as shown. If in equilibrium the body is in the shown configuration, ratio $M/m$ will be:

Write the conditions for equilibrium of a rigid body.

A mass $M= 40\ kg$ is fixed at the very edge of a long plank of mass $80\ kg$ and length $1\ m$ which is pivoted such that it is in equilibrium. How far (approx.) from the pivot should a mass of $100\ kg$ be attached so that the plank starts rotating with an angular acceleration of $1\ rad/s^2$?

The resultant of the system in the figure is a force of $8N$ parallel to the given force through $R$. The value of $PR$ equals to
