Statics and Dynamics 1. The diagram below shows the loading on one of the horizontal floor beams and associated supporting vertical columns for a proposed building‚ sited on an incline. In order to consider the worst case‚ assume that the beam is simply supported and the column is pin jointed at either end. 1.1 Determine the beam reaction forces at each support and . Taking moments around (2 x 50) + (6 x 70) + (10 x 20) = (8 x ∴ = = 90 KN So‚ = 50 + 70 + 20 = + 90

therefore be deflected. * This can be shown by 3 facts: * They leave –ve charge on the surfaces they strike * They are deflected by magnetic fields as predicted by the right hand rule. Force experienced is F=qvB. The path of deflection is circular * They are deflected by electrically charged plates (capacitor) when it is placed on the inside of the cathode ray tube. Force experienced is F=qE. The path followed is parabolic MANIPULATIONS: Cathode rays can be manipulated

Introduction Vibration based energy harvesting has been investigated by several researchers over the last few years and cantilever beams with piezoelectric material layers are employed in electronic circuits as piezoelectric energy harvester due to its simple configuration. With the advancement in the electronics‚ interest in piezoelectric wireless sensors has increased manifold and various researches has been conducted to optimize the harvested energy for the proper and efficient functioning of

to think of the atom as a positively charged cloud with electrons randomly scattered in it. Rutherford later found this model to be false from his metal foil experiments because the large deflections of the alpha particles could only occur with a large‚ concentrated mass at the center of the atom. This supported the idea that there was a nucleus‚ a dense center of protons and neutron. b) Nuclear Models (Rutherford) The nuclear model supports a dense nucleus containing protons and neutrons‚ with
