What will be the angle of reflection when angle of incidence is 60? = 90 – 60 = 30 degrees. Since, angle of incidence = angle of reflection = 30 degrees. The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). The reflected ray […]

What is effective overburden pressure? When the soil is subjected to some load, it transfers the load to water in the pores and soil grains. This is defined as effective overburden pressure and otherwise will be called as inter-granular stress or effective stress. It increases with increasing depth of soil. What is Geostatic pressure? 1. […]

Do turbo engines have more problems? Turbo engines tend to have more problems in many cars, although there are turbocharged engines that are reliable. A turbocharged engine has more components than a naturally-aspirated (non-turbo) motor. A turbocharger itself is not uncommon to fail. The more parts, the more can go wrong. How long should you […]
