1.	In steel, the Young's modulus and the strain at the breaking point are 2 xx 10^(11) Nm^(-2) and 0.15 respectively. The stress at the breaking point for steel is therefore……………. .
Answer» `2 xx 10^(8) NM^(-2)` `3 xx 10^(10) Nm^(-2)` `3 xx 10^(12) Nm^(-2)` NONE of these Solution :BREAKING stress = Breaking strain `xx` Young.s MODULUS `= 0.15 xx 2 xx 10^(11)= 3 xx 10^(10) Nm^(-2)`
