Embibe Experts Solutions for Chapter: Statics, Exercise 1: Exercise 1

Two masses $m_1$ and $m_2$ are placed on a smooth horizontal surface and are connected by a string of negligible mass. A horizontal force F is applied on the mass $m_2$ as show in the figure. The tension in the string is

A wire elongates by $1 \mathrm{mm}$ when a load $W$ is hanged from it. If this wire goes over a pulley and two weights $W$ each is hung at two ends, the elongation of wire will be

With what minimum acceleration can a fireman slide down a rope while breaking straight of the rope is $\frac{2}{3}$ of the weight?

Two masses connected in series with two massless strings are hanging from a support as shown in the figure. Find the tension in the upper string

If$XYZ$is an equilateral triangle, then the resultant of the three forces, as shown in the figure is


           

A body of mass $10 \mathrm{kg}$ is acted upon by two forces each of magnitude $10 \mathrm{N}$ making an angle of $60°$ with each other. Find the net acceleration of the body.

Sum of magnitude of two forces is 25N. The resultant of these forces is normal to the smaller force and has a magnitude of 10N. Then the force are

Three forces acting on a body are shown in the figure. To have the resultant force only along the y-direction, the magnitude of the minimum additional force needed is -
