Explanation of common terms of sling
φ： Refers to the diameter of the circle;
2. N/mm2: refers to the tensile force per unit area;
3. Load: refers to the mass of the object applied on the sling;
4. Prestress: refers to the stress applied to the component before bearing the load;
5. Safety factor: refers to the ratio of product allowable load to design load;
6. Yield strength: refers to the maximum stress tensile strength that the sample can bear when yielding occurs;
7. Tensile strength: refers to the maximum stress that the sample can bear before breaking;
8. Reduction of area: refers to the percentage of the maximum reduction of the cross sectional area at the necking point and the original cross sectional area after the sample is pulled.
9. Impact energy: refers to the energy absorbed by the specimen of specified shape and size when it is broken under the impact test force.
10. Elastic modulus: refers to the proportional constant related to the material, that is, elastic modulus=stress/strain.
11. Elongation: refers to the percentage of total elongation and original gauge length of the tested material after tensile fracture under stress.
