Figure (PageIndex three ): The lead angle of a screw is definitely the angle on the thread that the nut are going to be climbing up since the shaft rotates. Once we locate the lead angle, we could draw a free system diagram of the "nut" within our unwrapped process.
The shank could be the extensive, cylindrical Element of the screw that extends from the head to the idea. It might be absolutely threaded or partly threaded, depending on the supposed use.

The force-velocity, or PV issue, will be the product with the strain and velocity between the nut and screw. It can help decide the load, velocity and obligation cycle which the nut can take care of. Plastic supplies have an intrinsic PV ranking, the point at which frictional warmth leads to long-lasting deformation on the plastic. So the greater load applied to a lead screw assembly, the slower it needs to be turned in order to avoid exceeding the nut’s PV Restrict.
