If bending low carbon steel pipe to 90 (right angle) you need to add another 5 for it to spring back.
The weight of a round stainless steel (SS) bar can be calculated using the formula: [ \text{Weight (kg)} = \frac{\pi \times (d/2)^2 \times L \times \rho}{1000} ] where ( d ) is the diameter of the bar in millimeters, ( L ) is the length in meters, and ( \rho ) is the density of stainless steel (approximately 7.9 g/cm³ or 7900 kg/m³). This formula accounts for the volume of the bar and its density to determine its weight.
Use the formula for a cylinder to find out the volume. Then multiply the volume by the density of steel (about 7900 kg/m3 - but it may vary slightly depending on the type of steel).
The formula to calculate the minimum bending radius for steel is: Minimum Bending Radius = (T * Width) / (2 * K), where T is the thickness of the steel, Width is the overall width of the bend, and K is a factor based on the steel's tensile strength and type of steel.
The moment of inertia of a steel section depends on its shape and dimensions. It is a measure of its resistance to bending. It is often calculated using specific formulas for common geometric shapes like rectangles, circles, or I-beams. The moment of inertia is an important parameter in structural engineering for analyzing the bending behavior of steel beams and columns.
Curtailment is optimizing steel w.r.t changes in Bending moment over a section
My= As*Fy*Jd As= Area of steel reinforcement (tensile steel only) Fy= yield strength of steel Jd= moment arm
I searched for properties of 1" x 3" 11 gauge rectangular steel tubing, but that is an odd size. We will have to calculate the section modulus (excluding corner radius): S = bd^3 - b1d1^3/6d b = 1" d = 3" b1 = 1 - 2x0.091 = 0.818 d1 = 3 - 2x0.091 = 2.818 S = [(1 x 3^3) - (0.818 x 2.818^3)] / (6 x 3) = 0.483 in^3 M (maximum bending moment) = [P (point load) x l (length)] / 4 Solving for P: P = 4M/l M = s x S Where: s (allowable bending stress) = .55 x yield strength of steel To be conservative we will assume that the steel you have is 30,000 psi M = .55 x 30,000 x 0.483 = 7,969 in-lb P = 4 x 7,969 / 72 in = 442#
Assuming linear elastic bending with small deformations and planes perpendicular to the neutral axis remain plane after bending, then for a rectangular beam: Moment = (Yield Stress)*(Second Moment of Area)/(Distance of surface to Neutral Axis) For Ultimate Bending Moment, assume stress is uniform throughout the beam, and acting through half the distance from surface to neutral axis, then: Moment = Stress * (Area/2)*(h/4 + h/4) For a better visualization check out Popov's textbook, Engineering Mechanics of Solids, Chapter 6, Section 6.10
bar cranking is the process of bending up the bottom steel bars in upward direction. it is mainly to prevent upward bending moment near the joint. also useful for attaching stirrup bar efectivly. cranking is also used in two way slabs

To calculate the weight of a steel round, you can use the formula: weight = volume * density. The factor needed would be the density of steel, which is typically around 7850 kg/m³. By knowing the density and the volume of the steel round, you can easily calculate its weight.
The weight of an MS (mild steel) sheet can be calculated using the formula: Weight = Length (m) x Width (m) x Thickness (mm) x Density of steel (7.85 g/cm³) / 1000000. This formula will give you the weight of the MS sheet in kilograms.
The chemical formula for steel is Fe3C
