A rectangular plastic specimen with a cross-sectional area of $240 \mathrm{~mm}^{2}$ is subjected to tension with a force of $15000$ $\mathrm{N}$ resulting in elastic deformation. If the Young's modulus of the specimen is $34.55$ $\mathrm{MPa}$, the value of strain is $\_\_\_\_\_\_$ (rounded off to two decimal places).
