Mechanical Properties of Solids · Elasticity

Two wires as shown in the figure below, made of steel and have breaking stress of

12\times10^{8}\ \mathrm{N/m^2}

. Area of cross-section of upper wire is

0.008\ \mathrm{cm^2}

and of lower wire is

0.004\ \mathrm{cm^2}

. The maximum mass that can be added to pan without breaking any wire is kg. (take

g = 10\ \mathrm{m/s^2}

)
