The Young's modulus of a metal is 2×10^12dyne/cm^2 and its breaking stress is 11000kg/cm^2. In case of longitudinal strain the maximum energy that can be stored per cubic metre of this metal is approximately (assume g=10m/s^2) (1)58.25×10^5 (2)30.25×10^5 (3)37.15×10^5 (4)15.15×10^5 |

Answer» ngs modulus = Stress/strain along with the FORMULA,Energy Stored per unit VOLUME = (1/2)×stress×strain (with proper units)LOOK up hcv for DERIVATIONS! |
