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

Drion Shkreli Alchemy to Astrophysics Professor Efthimiades 12/11/2012 Quantum Mechanics Homework 1. Principles of Quantum Mechanics a. Particles have multiple virtual motions and each motion is accompanied by a wave. The strength of the total particle wave at each point corresponds to the probability that the particle may be found there. Applying this principle we can explain all kinds of phenomena‚ from the properties of atoms and radioactivity to light reflection. 2. Electron Double

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
