The tangent modulus of steel varies depending on if the steel has yielded.
If the steel has not yielded, and is still elastic (stresses less than approx. 275 MPa (39885 Psi) the tangent modulus will be equal to the Young's Modulus, 205 GPa (39885367)
If the steel has yielded, the tangent modulus will be related by the Ramsberg-Osgood Equation, but a reasonable value to use would be approx. 1.5 GPa (2175565 Psi)
what is the weight od 25x25x3 mm mild steel angle per meter
about 2mm mild steel max
Specifics of their alloys, they'll have different proportions of carbon, iron, chrome etc. These changes will make the one known as steel a little stronger and harder to machine than the one called mild steel.
section modulus of any section is the ratio of the moment of inertia to the distance of extreem fibre from the neutral axis. plastic section modulus is the section modulus when the cross section is subjected to loading such that the whole section is under yield load. numerically it is equal to the pdoduct of the half the cross section area and the distance of center of gravity of tension and compression area from neutral axis
nails, screws, nuts and bolts and car bodies
what is the flexural modulus value od mild steel
shear = 77GPa
Modulus is given in pounds per square inch (psi). For steel it is 30,000,000 psi
180 -220 Gpa similar to mild steel
the modulus for brass is 91*109 Nm-2
55
The secant modulus is the total stress or strain on an object as described by a stress-strain graph. The tangent modulus is the marginal strain.
30000000psi
because it is the ratio of the stress to the strain and in actual condition the strain developed is different from the theoretical .

mild steel is heavier
