In mechanical design, radial force, axial force, and circumferential force are three common forces. Correctly judging the direction of these forces is crucial for the design and analysis of mechanical systems. The following will introduce the definition, function, and judgment method of these three forces respectively. In actual design, the direction judgment of these forces is not only applicable to the analysis of a single part, but also to the optimization design of the entire mechanical system. For example, in the design of a reducer, the direction of radial force, circumferential f......

PETG has emerged as a popular material in the 3D printing industry. This article provides an overview of the PETG material, focusing on its properties, applications, printing settings, and differences between PLA and PETG filament. What Is PETG Material? Polyethylene Terephthalate Glycol (PETG) is a versatile thermoplastic polyester that is a modified form of polyethylene terephthalate (PET). The addition of glycol in the polymer structure enhances its clarity and reduces temperature sensitivity, making it easier to extrude. PETG combines the desirable qualities of both ABS (acrylonitri......

Buttress threads are a go-to solution for handling heavy axial loads in one direction, thanks to their unique trapezoidal design. With a steep “stabbing flank” and a shallower “bearing flank,” they provide high load capacity, reliable self-locking, and smooth engagement. You’ll find these threads in applications like screw jacks, clamps, hydraulic systems, and oilfield equipment, where strength and efficiency are key. Here, we’ll break down buttress thread dimensions in both metric (mm) and imperial (inch), cover the standard angles from ISO, ANSI, DIN, and API, and include a calculator......
