make the fat particles small enough to mix together with the watery components of the coconut milk. The samples of coconut milk subjected to higher pressure show a higher temperature with longer time interval‚ this is due to mechanical friction and shear force in the homogeniser. During this experiment a major precaution which had to be taken was not to allow the feed tank in the homogeniser to run out of liquid as this will cause a malfunction and would spoil the machine.

used as characteristic values -material property may have two characteristic values‚ the upper value and the lower value. In most cases only the lower value need be considered. However‚ higher values of the yield strength‚ for example‚ should be considered in special cases where over strength effects may produce a reduction in safety. -structure is deemed to be satisfactory if its design load effect does not exceed its

University of Technology Tapany Udomphol May-Aug 2007 Introduction • Torsion test is not widely accepted as much as tensile test. • Torsion tests are made on materials to determine such properties as the modulus of elasticity in shear‚ the torsion yield strength and the modulus of rupture. • Often used for testing brittle materials and can be tested in full-sized parts‚ i.e.‚ shafts‚ axles and twist drills which are subjected to torsional loading in service.

book is to describe both the basic hydrodynamics and the basic sediment transport mechanism. The reader’s background should be a basic course in wave theory and fluid mechanics. Chapter 1 deals with fundamentals in fluid mechanics with emphasis on bed shear stress by currents‚ while Chapter 3 discusses wave boundary layer theory. They are both written with a view to sediment transport. Sediment transport in rivers‚ cross-shore and longshore are dealt with in Chapters 2‚ 4 and 5‚ respectively. It is not

however small they may be. Conversely‚ it follows If a fluid is at rest‚ there can be no shearing forces acting‚ and‚ therefore‚ all forces in the fluid must be perpendicular to the planes upon which they act. Shear Stress in a Moving Fluid There is no shear stress in a fluid at rest; shear stresses are developed when the fluid is in motion. If the particles of the fluid move relative to each other so that they have different velocities‚ they cause the original shape of the fluid to become distorted

beam where the shear force is zero ( because V = dM/dx ). In contrast‚ nonuniform bending refers to flexure in the presence of shear forces‚ which means that the bending moment changes as we move along the axis of the beam. As an example of pure bending‚ consider a simple beam AB loaded by two couples M1| having the same magnitude hut acting in opposite directions (Fig. 1a). These loads produce a constant bending moment M = M1 throughout the length of the beam. Note that the shear force V is zero
