Compression and tension
The force forms of support rods mainly include compression and tension. When lifting cargo, the main force form of hydraulic support rods is compression. In clothes drying racks, the force form of support rods is mainly compression.
The working principle of support rods is to provide elastic support through the pressure of gas or liquid. The elastic coefficient of standard support rods is between 1.2 and 1.4, with a nearly linear elastic curve. This characteristic enables the support rods to provide stable support when stressed, especially when they need to bear heavy objects, such as hydraulic support rods in electric cranes.
The force forms of support rods in different types and application scenarios will be different. For example, when athletes perform pole vaulting, the support rods are mainly subjected to bending forces. In clothes drying racks, the support rods are mainly subjected to compression. These differences reflect the mechanical properties and design requirements of support rods in different applications.
