In this article, I will describe combined bending and direct and torsional stresses in shafts. For example, on a ship’s propeller shaft, it happens that the shaft is subjected to direct thrust in addition to bending moments and torsion. In this case, the forward and axial forces due to the bending moment must be combined … Read more
In this post, we will talk about Mackintosh Probe Test. The Macintosh probe test is used for research purposes, especially soil exploration. The Macintosh Probe Test is used to determine the bearing capacity, that is, the strength of the soil. The results obtained from the test provide a rough estimate of the soil layer at … Read more
What Is Circular Prestressing? Circular Prestressing is used to refer to the prestressing of circular elements such as pipes and tanks in which the prestressed wire is wound in a circle. In contrast to this term, “linear prestressing” is used to refer to any other type of prestressing in which a cable is straight or … Read more
The activated sludge process is a type of wastewater treatment process. The wastewater can be domestic or industrial. The activated sludge process uses aeration and biological flocs composed of bacteria and protozoa. The general scheme of a process for the removal of carbonaceous impurities using activated sludge includes the following elements: An aero tank in … Read more
In this article, I will discuss the Differences between Rapid Gravity Filters and Slow Sand Filters. The difference between the two lies not only in the filtration rate but also in the concept of the washing process. Slow sand filtration is a biological process in nature and rapid sand filtration is a physical cleaning process. … Read more

Summit curve Valley curve Definition of Summit Curve A summit curve is a type of vertical curve. It is given as a road or railroad when crossing a ridge or valley. Usually, … Read more
What is tacheometric surveying? The definition of tacheometric surveying cab be given as: In this type of surveying different measurements like vertical distance and horizontal distance are taken indirectly by taking only instrumental observation. Typically, tacheometric survey is used when high observation accuracy is not required. A survey is performed to create a contour map of the site. It can … Read more
Clay roof tiles are ceramic products made up of a single piece of clay or slate or both, given an arbitrary shape, usually rectangular, flat in the plastic state, and fired in a kiln. Clay roof tiles are made by firing molded clay. The density of this roof tile is determined by the time and … Read more
Glulam is the short form of glued laminated timber. Glulam is formed by laying down several wooden planks or boards and bonding them with a strong, moisture-resistant adhesive. Structural wood products with lightweight and bearing capacity comparable to steel. Properly made glued laminated timber is fire and earthquake-resistant. This type of wood is suitable for … Read more
Laminated veneer lumber is a high-strength engineered wood formed by bonding multiple layers of thin veneers layer by layer using an adhesive. is designed to take advantage of new species and small trees not available for hardwood production. Laminated veneer lumber is an economical and sustainable building material that provides high structural strength and reliability … Read more
