Screw method
Screw theory is the algebraic calculation of pairs of vectors, such as forces and moments or angular and linear velocity, that arise in the kinematics and dynamics of rigid bodies. The mathematical framework was developed by Sir Robert Stawell Ball in 1876 for application in kinematics and statics of mechanisms (rigid body mechanics). WebbThe allowable stresses and screw end force and the method of applying the force in the calculation of the tensile stress are not considered on this page but are addressed on this site by tables and more importantly referenced links If a screw threaded fastener is to fail it is preferable that the screw fails rather than the internal or external thread strips.

WebbThe repair method is as follows: (1) The diameter of extruder screw and barrel increases due to wear. If there is still a certain nitriding layer, you can directly drill a hole in the barrel, grind to a new diameter, and then prepare a new screw according to this diameter. WebbAnchor the device to the bone with a screw inserted through the articulated footplate and insert the hook on the device into the hole at the end of the plate. As the tensioning screw is then tightened, the two limbs of the device are pulled together, and compression is achieved at the fracture site. Distraction
