Steel is an outstanding structural material. It has a high elastic modulus, which results in small deformations under load.
举一反三
- Which of the following statements are correct? A: The greater the modulus, the stiffer the material. B: The stiffer the material, the higher the resistance of the material to deformation. C: The higher the magnitude of elastic modulus, the higher the magnitude of the inter-atomic bonding forces in a material. D: The higher the magnitude of elastic modulus, the lower the magnitude of the intermolecular bonding forces in a material.
- 5. (5.0 points )Steel is outstanding as a structural material, because it never deforms and can thus be used in skyscrapers.
- The critical pressure of the compression bar is directly proportional to the elastic modulus of the material
- In conventional reinforced concrete, the high tensile strength of steel is combine with concrete's great ________________ to form a structural material that is strong in both ________ and ________.
- Based on the assumption of homogenousity (匀质性),( ) is the same over the loaded body. A: stress B: strain C: elastic modulus of the material D: displacement
