Squared and grounded spring


Extracted text: For a weighing machine, the allowable load of 3000 N is loaded on a helical spring which it resulted deflection of 60 mm. The spring is made of chrome vanadium steel and factor of safety is equal to 2. The spring index is 4. Wahl stress factor is considered for the direct shear and change in curvature of the compression spring. Given =69 GPa and G = 79.34 GPa. a) Justify whether the spring can be slot into the spring housing with diameter of 42 mm. b) Determine the total number of coil.
