grades to compare different particle size distributions – from wide to very narrow. Dextrose was used because of its wide size distribution and by sieving analysis‚ sections from particle size distribution were removed to be tested in the shear tester. Sodium chloride and maltodextrin have a narrower particle size distributions and the presence of very fine particles gave us the possibility to study the effect of particles below 45 m. Three samples were tested for each flow property measurement

The longbow has been used over the years‚ first as a weapon to hunt‚ later as a war weapon‚ and now its used as a sport‚ but its physics had always been the same over the years‚ regardless of its use. This physics involves two components: bow mechanics and arrow flightBow mechanics: when an archer pulls back the string‚ he does work on the bow‚ and is converted to potential energy. Upon release of the arrow‚ this potential energy is converted into kinetic energy‚ most of which is transferred to the

True slump occurs when the concrete remains in mainly the same shape with maybe a minor slump taking place‚ and is the only test of use. Shear Slump occurs when the top of the mix comes off and slips towards the side. During a collapse slump the concrete completely falls or collapses. If the later of the slumps occur‚ in the case of the shear slump‚ a new sample should be taken and the test should be repeated. A collapse slump will show that the mixture is too wet and the workability of

Literature Review Kevin‚ this is largely unfinished with some of the journals which I have written about not being relevant. My main basis of literature review will be on Terzaghi‚ vesic‚ a thesis‚ and lau and Bolton. Terzaghi‚ K. (1943). Theoretical soil mechanics. New York: Wiley In this book‚ Terzaghi introduces the idea of bearing capacities‚ the critical load over a given area which a soil takes to fail. The concept of bearing capacities became fundamental in determining the ultimate

the external force is no longer applied. There are various elastic moduli‚ such as Young’s modulus‚ the shear modulus‚ and the bulk modulus‚ all of which are measures of the inherent stiffness of a material as a resistance to deformation under an applied load. The various moduli apply to different kinds of deformation. For instance‚ Young’s modulus applies to uniform extension‚ whereas the shear modulus applies to shearing. The elasticity of materials is described by a stress-strain curve‚ which
