the contact pressure between two bodies. Suspension bridges are good example of structures that carry these stresses. The weight of the vehicle is carried by the bridge deck and passes the force to the stringers (vertical cables)‚ which in turn‚ supported by the main suspension cables. The suspension cables then transferred the force into bridge towers. wofkim@yahoo.com ^^ Normal Stress Stress Stress is the expression of force applied to a unit area of surface. It is measured in psi (English unit)

Abstract This experiment is conducted to measure the transverse bending deflection of the tie bar and at the same time comparing it to the theoretical values. The two theoretical formulae to get the central deflection in this experiment are simple theory method and exact formula. By comparing these formulas to the experimental formula‚ the most suitable method to measure the central of deflection could be obtained. This experiment is then continued by measuring the adequateness of the

Thomson’s bar magnet method. Basic methodology: Electrons in a CRT are deflected in the vertical direction by applying a potential between the vertical deflection plates of the CRT. A magnetic field perpendicular to the deflecting electric field is produced using a pair of bar magnets. The position of the magnets is adjusted so as to cancel the deflection of the electrons. The knowledge of the deflecting potential and the magnet field of the bar magnets leads to a calculation of the specific charge. I

microscopy professor: Ernesto Suarez by ananthalakshmi adapa University of Hartford What is a electron microscopy? An electron microscope (EM) is a type of microscope that uses an electron beam to illuminate a specimen and produce a magnified image. An EM has greater resolving power than a light microscope and can reveal the structure of smaller objects because electrons have wavelengths about 100‚000 times shorter than visible light photons

Integrated Mechanical Testing Laboratory BUCKLING OF A COLUMN Objective The primary purpose of this experiment is to verify the critical load for buckling‚ relationship among the bending-moment and deflections‚ for different end conditions when a rectangular beam is subjected to axial loading. Theory A column is a member subjected to axial compressive forces. When a column is concentrically loaded‚ it is expected to reach its yield stress. But usually prior to yielding‚ when
