Tube rectangular of square tubing is the measure of the amount of force that is applied to a square tube in order to cause it to bend. Bending moment for square tubing is calculated by multiplying the applied force by the distance from the point of application to the center of the tube. The bending moment of square tubing is affected by the material properties of the tube, the dimensions and shape of the tube, and the applied force. Bending moment can significantly affect the strength of square tubing. If the bending moment exceeds the tube's strength, it can cause the tube to permanently deform or even break. The most commonly used unit for measuring bending moment in square tubing is pound-force per inch.

The experimental pressure or eddy currents should conform to the sample size rules. The mechanical properties of steel are an important way to guarantee the steel, depending on the chemical composition of the steel and the system heat treatment. , tensile properties as well as hardness and toughness indicators, as well as high temperature and low temperature properties required by users, are also set according to different application requirements.1 Tensile Strength The tensile strength of the sample during the stretching process, the maximum force received during the fracture process, the stress obtained from the original cross section of the sample, called tensile strength, which means that the metal data can resist the tensile force. The greatest talent. The calculation formula is: metal data with elasticity phenomenon. When the force does not increase during the stretching process, the stress of the sample can continue to expand, which is called the yield strength. If the force hits the ground, the strain limits Upper and lower elasticity must be determined. Maximum stress before and under the initial drop of the sample; the minimum stress at the elastic stage when calculating the initial transient effect
