Slings with common terminology

The sling refers to a force-removing tool tied between a hoisting machine and a hoisted object, and a force-receiving member for stabilizing a space structure in order to move an object.

1. φ: refers to the diameter of the circle;

2, N / mm2: refers to the unit area can withstand the pull value;

3, load: refers to the quality of the object imposed on the sling;

4. Prestress: refers to the stress that the component has applied before it receives the load;

5, safety factor: refers to the ratio of product allowable load and design load;

6, the yield strength: refers to the sample in the yield phenomenon when the maximum stress can withstand the tensile strength;

7. Tensile strength: refers to the maximum stress value that the sample can withstand before breaking.

8. Reduction of area: refers to the percentage of the maximum reduction of the cross-sectional area of ​​the constricted neck and the original cross-sectional area after the specimen is broken.

9, impact work: refers to the provisions of the shape and size of the sample in the impact of the test force under the effect of a break when the work absorbed.

10. Elastic Modulus: Refers to the proportional constant associated with the material, ie: Elastic Modulus = Stress/Strain.

11, elongation: refers to the test material in the tensile fracture, the total elongation and the original gauge length percentage.
