different loading and support conditions are covered. Expressions for properties of geometrical figures are also given, together with useful mathematical solutions.
The preload stress can be calculated from the tightening torque using: Where: T = applied torque. K = torque coefficient (typically between 0.2 and 0.3, depending on lubrication and bolt material) dnom = nominal diameter of the bolt. Typically, bolt preload is about 70% of the bolt’s ultimate tensile strength the bolt.
8 sty 1993 · The standarized properties of metric bolts are specified in the international standard ISO 898-1:2009 'Mechanical properties of fasteners made of carbon steel and alloy steel - Part 1: Bolts, screws and studs with specified property classes - Coarse thread and fine pitch thread'.
16 lis 2018 · The average stress in the rod would be $$\left. \sigma = \frac{F}{A} \;\right\} F \leq \sigma_{\rm yield\,} A$$ Where $F$ is the axial load applied, and $A=\frac{\pi}{4} d^2$ is the cross-sectional area.
Bearing Area Stress Equation for Plate and Bolt or Pin. B t = F / (t d) Where: B t = Bearing Area Stress Area ( N/mm 2, lbs/in 2) F = Applied Force (N, lbs) t = Thickness (mm, in) d = Diameter (mm, in) Factor of Safety. Factor of Safety = F.S = ultimate stress / allowable stress.
Example 3.1 A 5 x ½ bar of A572 Gr. 50 steel is used as a tension member. It is connected to a gusset plate with six 7/8 in. diameter bolts as shown in below. Assume that the effective net area Ae equals the actual net area An and compute the tensile design strength of the member. b b a a 5 x ½ in. bar Gusset plate 7/8 in. diameter bolt A572 ...
