Many materials of a structure are subjected to loads during use, such as the wings of airplanes and the shafts of automobiles. Under load conditions, it is necessary to know the characteristics of the material used so that the resulting deformation is not excessive and failure does not occur. The mechanical behavior of the material […]
In learning about oil and gas, we must often hear the terms onshore and offshore. So, what do these two terms mean? Let’s discuss! Onshore is work on land to shoreline areas for oil and gas exploration and exploitation activities. Examples of onshore work are onshore refineries and boreholes. While offshore means work that is […]
Material and energy balances are based on a conservation law which is stated generally in the form: Change in total energy in the system = Total energy entering the system (Input) – Total energy leaving the system (Output) Energy is the total energy of a system. The total energy of a system can be in […]
It is undeniable, in this modern era, the need for electricity seems to be a primary need for the running of the economy, industry and our daily lives. One type of power plant that quite dominates the supply of electricity needs in the world or in Indonesia is a steam power plant. The use of […]
Water turbines are often used in hydroelectric power plants. The turbine has the function of changing the potential energy possessed by the water into mechanical energy (rotation) in the turbine rotor. The mechanical energy of the turbine is connected to a generator to generate electricity. The working principle of a water turbine is the utilization […]
To design an airplane wing or scale model, some knowledge of aerodynamics and terminology (terms) commonly used in aviation is required. In principle, airplanes use wings to generate lift. As for producing the lift, the airplane wing utilizes two main principles, first, namely the pressure difference between the top and bottom surfaces of the wing, […]
