Elastic modulus is a general term for the ratio of stress to strain in materials, while Young's modulus specifically measures this ratio for linear elastic deformation under tension or compression.
What is the correct statement of the following options? A、杨氏弹性模量E仅决定于材料本身的性质,模量越大,物体越不容易变形。 Young's modulus of elasticity e only depends on the properties of the material itself. The larger the modulus is, the less likely the object is to deform. B、杨氏弹性...
teel bolts with a diameter of 10 mm are surrounded by bronze sleeves. The outer diameter of the sleeve is 20 mm and the inner diameter is 10 mm. The elastic modulus of steel and bronze are 200 GPa and 100 GPa respectively. If the bolt is subjected to a p
