What is the tensile force of the galvanized flat steel of 20*3?
According to "hot rolled flat steel size, shape, weight and allowable deviation", GB 704-88:Ordinary class allows upper deviation +0.3mm, lower deviation -0.5mm; higher allowed upper deviation +0.2mm, lower deviation -0.4mm, the upper deviation is not to think, do not exceed the next deviation is good.
Since the specifications require that the stationary support be able to withstand the 49N pull, I wonder if this flat steel can withstand such a large pull to choose the flat type;
