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 cause(s) of road accident in developing countries is the mechanic who repairs the various vehicles before the vehicles hits the road. Though many attempted to suggest that a vehicle which is not roadworthy is a source of accident‚ they failed to propose means by which this could be rectified in a holistic way. Laws could be enacted to prevent vehicles not roadworthy from operating on the roads but between the two gaps the mechanic plays a significant role in preventing such road accidents occurring

CEIC2001 – Fluid Mechanics Notes Fluid – A substance which is capable of flowing. A fluid is also a substance which has no permanent resistance to change in shape i.e. a solid can resist a shear stress‚ τ by static deflection; a fluid cannot‚ any shear stress applied to a fluid will result in the motion of that fluid for as long as the shear stress is applied. τ=FA Where F = force which is tangent to a surface (shear force)‚ A = area of moving plate in which shear force is applied to.

Quantum Mechanics Notes Matter can be understood by applying two scientific models: particles‚ and waves Particle Models Particles are objects that are hard‚ have mass‚ and move according to Newtonian mechanics. Particles are a macroscopsic model which can be applied to the microscopic world. Kinetic model of a gas: gas molecules are small‚ hard particles bouncing off of one another and the walls of their container. Macroscopic phenomena of pressure and volume are explained in terms of masses

EXAM 1 NOTES The actual pressure at a given position is called the absolute pressure‚ and it is measured relative to absolute vacuum (i.e.‚ absolute zero pressure). Most pressure-measuring devices‚ however‚ are calibrated to read zero in the atmosphere (Fig. 3–2)‚ and so they indicate the difference between the absolute pressure and the local atmospheric pressure. This difference is called the gage pressure. Pgage = Pabs - Patm The pressure at a point in a fluid has the same magnitude in all

punctuation-you can do it!! Classical Conditioning and Operant Conditioning Phobias in a human being are a very powerful thing. So powerful that they can be developed at a very early age‚ and affect the rest of our lives. There are many types of phobias‚ some are more common than others‚ such as heights‚ insects‚ or needles. I have also seen phobias as weird as pickles and rabbits! Despite how weird a phobia might be‚ these phobias have developed a certain way: Through classical or operant conditioning

Isaac Newton (Father of Classical Physics) Newton was known as a natural philosopher during his life but his theories of motion‚ gravity‚ light‚ etc formed the cornerstone of what would become known as physics. He probably contributed more to the science than any single person before or after him. Newton’s 1687 publication of the Principia is considered to be among the most influential books in the history of science‚ laying the groundwork for most of classical mechanics. In this work‚ Newton described
