Introduction Rolling friction and rolling resistance refer to the force that helps to resist the rolling motion of the machinery body of the surface. For example, it is commonly seen that pulling a heavy almirah on a rough surface is so tough but if an iron wheel is used then ... Read More

Introduction Human Physiology, a part of biology concerned with the functioning of living organisms and their parts, is studying how the body works. The body's structure, function, and chemistry are all closely related to one another. The body comprises many systems that work together to maintain homeostasis. These systems ... Read More

Introduction A degree in chemical engineering helps in giving the theoretical and practical knowledge that is needed to get registered as a professional chemical engineer. The course may specifically centre on the modelling of chemical processes and mechanics of fluid. A Chemical engineering course is extremely feasible for the candidates ... Read More

Introduction The rolling motion refers to the combination of a type of translation motion as well as a rotational motion of an object. For example, in a machinery body, the rolling motion differs from the mass centre motion, which also signifies a type of translation motion of that particular ... Read More

Introduction The human population is the measure of people who live in a certain region or country. The population can be recorded by the number of people living in a particular area or place (such as a city, state, or country), and by the density of the population in ... Read More
