A beam has a cross-section shown in Fig. SOM-FJ-29. It is subjected to a normal tensile force, P. whose line of action passes through the centroid of the horizontal flange. Allowable bending stresses are 180 MPa in tensions and 80 MPa in compression. All dimensions are in mm. Determine the location of the neutral axis of the section as measured from the top of the flange. 180 18 N.A. 180 %3D %3D Fig. SOM-FJ-29 %3D %3D %3D 18

Alloys

An alloy is an admixture of two or more metals or a metal and a non-metal. Since ancient times, man has been using alloys. Alloying helps to retain the properties of the parent matter, such as hardness, strength, toughness, ductility and is corrosion-resistant. Copper alloys such as brass have antimicrobial properties that help to fight against (Coronavirus disease 2019) COVID-19 and other hospital-acquired infections. Some common alloys are brass, bronze, solder steel, etc. Most alloys have a lower melting point than their constituents. This is due to the presence of a nonmetal as one of the constituents that behaves as an impurity and restricts the raise of melting point.
