Title: Mass Moment of Inertia Objective: To determine mass moment of inertia of a part using experimental method. Theory: If a part has been designed and built‚ its mass moment of inertia can be determined approximately by a simple experiment. This requires that the part be swung about any axis (other than one that passes through its CG) parallel to that about which the moment is sought and its period of pendular oscillation measured. Figure 1 shows a part of connecting rod suspended on a knife-edge

AIR QUALITY IMPACT ASSESSMENT REPORT OF THE PROPOSED BASE TRANSCEIVER STATION (BTS) October‚ 2012 1.0 Introduction The sources of ambient air pollution‚ especially in urban environments‚ are often quite diverse. These sources can be broadly classified as stationary‚ mobile and area emission sources. Emissions of pollution from these three classes of sources typically result in complex spatial and temporal distributions of ambient air pollution concentrations. Emission inventories form

Segregation is caused by * Too wet mix‚ extremely high workability or less cohesive mixture causes the mixture unable to hold heavy aggregate * Dropping from excessive height * Over compaction of fresh concrete. Two methods to minimize segregation in fresh concrete: * Adequate workability is enough. * Don’t over

Vol. 1 ACETIC ACID 115 ACETIC ACID 1. Introduction Acetic acid [64-19-7]‚ CH3COOH‚ is a corrosive organic acid having a sharp odor‚ burning taste‚ and pernicious blistering properties. It is found in ocean water‚ oilfield brines‚ rain‚ and at trace concentrations in many plant and animal liquids. It is central to all biological energy pathways. Fermentation of fruit and vegetable juices yields 2–12% acetic acid solutions‚ usually called vinegar (qv). Any sugar-containing sap or juice can
