Force on submerged surfaces can either be on an inclined or a horizontal plane. A body submerged in a fluid always has a force acting on it due to hydrostatic pressure. As such, these forces are known as hydrostatic forces. A single surface point of force emanates from a planar...

Snell’s law or the Law of Refraction is .Consider a light ray which travels from fixed points P to Q. The ray will choose the quickest route (through the point X, which is not fixed) and so minimize the time of travel. The light ray has velocity CA in medium...

A piston is manufactured mostly using cast aluminium alloys. Rings are made using either cast iron or stainless steel. The manufacturing process depends on the intended application of the piston. The most common process is through casting. Typically, casting process involves pouring molten metal into a mould with a design...

In order to establish the integrity of multi-storey buildings, three key design philosophies are used: permissible stress; load factor; and limit state approach. The approaches are important as they facilitate the attainment of serviceability, economy, safety and functionality conditions. The approaches are elaborated further below. Permissible stress method             Bhavikatti (2010) notes...

Technological Trend in Civil Engineering As a result of the current technological trend in civil engineering, there are notable improvements on such a field of engineering. Consequently, Civil engineering transforms because information technology captures the geometrical perspectives and the latter is permanent with a growing trend. Interest in Civil Engineering and Information...

Beams are structural elements designed to bear structural load (dead load) and other external loads (live loads).  Bending moment of a beam denotes a reaction that a structural beam produces when an external force is applied on the beam causing its bending. In civil engineering the bending moment is referred...

A truss is a structure consisting of beams that are triangularly connected and applied in costructing buildings and bridges (Taranath, 2016). A framework comprising of cross-members that are connected using pin joints and supported at both ends using rollers or hinged joints is considered to be statically determinate (Hibbeler, 2015)....

Over the years and in recent times a couple of technologies have been developed in the field of aerospace engineering which has modernised the lives of aviation service users. There is need to mention that the two division of aerospace engineering is regarded as astronautic, and the Aeronautical engineering. The...

Building construction is a rewarding, significant but complex process. The construction project usually begins with a concept and ends in a structure that might house people for many years. Nevertheless, the planning stage of the construction projects needs an orderly and well-planned assembly of all the needed resources. Articulation of...

This experiment was conducted in order to assess the relationship between the Reynolds number and friction coefficient for two pipe having different cross-sectional areas. The other aim was to investigate the effect of fluid density on the Reynolds number. Different flow rates were set at a laminar flow of water...

This section analyses calculated values of time constant and capacitance. The current and voltage of discharging capacitor are measured for a period of 90 seconds and listed in Table 1.1. From this table, voltage is plotted against time as shown in Figure 1.9. Analysis of errors and uncertainties was not possible...

In recent years, most construction of buildings is conducted using both the ancient and modern methods. Buildings existed from long ago history which were constructed mainly for reasons of shelter provision. However, modern buildings have undergone revolutionary changes including the use of various types of construction materials such as timber,...
