Web7 apr. 2024 · The stress at the critical point of the helical wire is investigated based on the model by considering the local flexure. The results indicate that the present model can well simulate the bending stiffness variation during irregular response, which has significant effect on the stress of helical wire. Download to read the full article text Web18 aug. 2024 · An open coiled helical spring of wire diameter 12 mm, mean coil radius 84 mm, helix angle 20° carries an axial load of 480 N. Determines the shear stress and direct stress developed at the inner radius of the coil. Given, Diameter of wire (d)= 12 mm = 0.012m. Mean coil radius (R)= 84 mm = 0.084m. Helix angle (α)= 20° Axial load (W)= …
