Two masses $ m_{1}=5\,kg $ and $ m_{2}=4.8\,kg $ tied to a string are hanging over a light frictionless pulley. What is the acceleration of the masses when lift is free to move ? $ (g=9.8 \, m/s^{2}) $

A weight $w$ is suspended from the midpoint of a rope, whose ends are at the same level. In order to make the rope perfectly horizontal, the force applied to each of its ends must be:

The force required to just move a body up an inclined plane is double the force required to just prevent it from sliding down. If $\theta$ is the angle of friction and $\theta$ is the angle which the plane makes with the horizontal, then :

Two forces of $12\,N $ and $8\,N$ act upon a body. The resultant force on the body has a maximum value of :

A man weighing $60\, kg$ is in a lift moving down with an acceleration of $1.8\, m/s^2$. The floor exerts on him a force equal to :
