WebJul 28, 2024 · Finding the lead angle is the first step in analyzing a power screw system. Figure 6.4.3: The lead angle of a screw is the angle of the thread that the nut will be climbing up as the shaft rotates. Once we find the lead angle, we can draw a free body diagram of the "nut" in our unwrapped system. Here we include the pushing force which … WebThe screw shaft snaps. So you use the screw material to get your elastic modulus for tension and for shear. Then you calculate the total area the force would be applied against (the screw shaft area for tension or the combine area of thread contact for shear).
