Mechanics of Materials-Deflection - Civil Engineering
www.learncivilengineering.comMechanics of Materials-Deflection Beam Deflections The deformation of a beam is usually expressed in terms of its deflection from its original unloaded position. Beams deflect (or sag) under load. Even the strongest, most substantial beam imaginable will deflect under its own weight. Under
Materials Soil classification - Learn Civil Engineering
www.learncivilengineering.comtesting of the soil, but it gives the engineer the general behavior of the soil. The Unified Soil Classification System (USCS) and the American Association of State Highway and Transportation Officials (AASHTO) system are the common classification system we use in civil engineering practice. Learning objectives: 1. Background of soil classification
BEST RIGGING PRACTICES IN LIFTING OPERATIONS, …
www.learncivilengineering.comConstruction operations And methods **Lifting and rigging** A crane is designed to lift a load by using ropes or chains. The load must be properly attached using a rigging system. There will definitely be a couple questions on the PE exam about lifting and rigging so make sure to do multiple practice questions.
Excavation and embankment (cut and fill)
www.learncivilengineering.comExcavation and embankment (cut and fill) Excavation = the removal of soil or rock from its natural location. Embankment = the placement and compaction of layers of earth or rock to form a roadbed of the planned shape, density, and profile grade. Various sections of a roadway design will require bringing in earth.
QUANTITY TAKE-OFF - Learn Civil Engineering
www.learncivilengineering.comQUANTITY TAKE-OFF ROOFING Roof material quantity take-off are pretty easy trig problems, but I will go over it quick to make sure you get it, because most likely a question will be on the PE exam. Trick of the Trade #4: When thinking of roof problems you just need to worry about three things. 1.The angle of the roof, or the rise/run of the roof
Phase relationship in Soil - Learn Civil Engineering
www.learncivilengineering.comPhase relationship in Soil This represents the soil that you take from a borrow pit. It is made up of AIR, WATER, and SOLIDS. So if you separated the soil into its components it would look like this. It is referred to as a Soil Phase Diagram. When looking at a Soil Phase Diagram you think of it two ways, 1. Volume, 2. Mass. AIR WATER SOIL AIR ...
