Descriptive research does not fit neatly into the definition of either quantitative or qualitative research methodologies‚ but instead it can utilize elements of both‚ often within the same study. The term descriptive research refers to the type of research question‚ design‚ and data analysis that will be applied to a given topic. Descriptive statistics tell what is‚ while inferential statistics try to determine cause and effect. Three main purposes of research are to describe‚ explain‚ and validate

Chapter Objectives To show how to use the method of sections for determining the internal loadings in a member. To introduce the concepts of normal and shear stress. To analyse and design members subject to axial load and direct shear. To define normal and shear strain‚ and show how they can be determined for various types of problems.

Chapter 8 Flow in Pipes 8-76E Solution The flow rate through a piping system between a river and a storage tank is given. The power input to the pump is to be determined. Assumptions 1 The flow is steady and incompressible. 2 The entrance effects are negligible‚ and thus the flow is fully developed. 3 The flow is turbulent so that the tabulated value of the loss coefficients can be used (to be verified). 4 The elevation difference between the free surfaces of the tank and the river remains constant

“The planter‚ the farmer‚ the mechanic‚ and the laborer‚ form the great body of the people of the United States‚ they are the bone and sinew of the country men who love liberty and desire nothing but equal rights and equal laws.” A diesel mechanic specializes in repairing and maintain diesel engines. Diesel engines are used in vehicles from trains to ships to buses and trucks. Not only does a diesel mechanic use the basic tools of the mechanic’s trade such as screwdrivers‚ wrenches and drills‚ but

WHAT IS FLUID MECHANICS ? FLUIED: Any thing whose particles can move easily from one place to another that means shape can be easily changed upon the application of negligible force. MECHANICS: Study of response of bodies upon the application of force. FLUID MECHANICS : Fluid mechanics may be defined as the branch of engineering science which deal with behavior of fluids under the condition of rest and

Have you ever wondered how hard it would be to become an automotive mechanic? Automotive mechanics is a very hard work field to get into‚ and helps you to save money in the long run. Within the field‚ you work very hard and work very long hours. Being an automotive mechanic is a good choice because of job security‚ pay‚ and not much schooling is required. The main reason why I think people go into automotive mechanics is because you don’t need much schooling; therefore‚ it’s an easy work force to
