HOW TO INCREASE OR DECREASE SEGMENTS OF A CIRCLE OR AN ARC IN GOOGLE SKETCHUP??

we can increase the number of segments of a circle or an arc right after activating the tool by pressing "ctrl +" or decrease it with "ctrl -" or we can simply set an exact number of segments of a circle or an arc if we type a value and push enter right after activating the tool or even after creating the circle by typing the value followed by the letter "s".

AutoCAD: Manage Layers with the LAYWALK command

Image
LAYWALK is a command that allows us to handle layers. You can access it by going to Home tab> Layers panel (expanded)> Layer Walk. or you can just type LAYWALK in the command line. It opens a dialog where we can see all the layers listed. The objects on the highlighted layers will be shown on the screen. In case we have a lot of layers we can use the filter bar to only show the ones we want. By entering c*, I can display only layers starting with the letter “c”. If you select a layer that has no objects on it, you can click the Purge button to purge the layer. Selecting a layer or several layers , you can right-click in the dialog box and choose Inspect to display the information about the layers and the amount of objects contained. We have also the option to "restore on exit" or not. If restore on exit is active, it means that when we close the LAYWALK window, the layer state will go back to how it was before running the command,  However, you can uncheck that check bo

HOW BAR IS PLACED IN BEAM AND HOW TO CALCULATE CUTTING LENGTH OF BARS??

Image
BENDING MOMENT DIAGRAM: The beam in center under stress is deflected. The incident creates positive moment in the middle of foundation base ( sagging ) & a negative bending moment ( hogging ) at top surface of the support. The positive moment which is called sagging developed at mid of the span The negative moment which is called hogging develops at the support. Requirement of steel will be more near supports where negative bending moment will act (above N.A) similarly requirement of steel will be more at center of the beam where positive bending moment will act (below N.A). The bending moment will be maximum at the center of the beam.  Point of contraflexure is the safest zone because at that point moment and shear is zero. TYPES OF BARS IN BEAM: Top main bars. Bottom main bars. Top extra bars. Bottom extra bars. Minimum 4 numbers of bars are provided ( 2 top main bars & 2 bottom main bars ). 1. Top main bars:              Given data, Beam size = 250mm x 300mm column size = 30

HOW TO CALCULATE WEIGHT OF STEEL BARS??

Image
Most Indian TMT bars usually have a standard length of 12m or 40ft. The diameter is variable ranging from 6mm to 40mm depending upon the usage requirements i.e 6mm, 8mm ,10mm, 12mm ,16mm ,20mm ,25mm ,28mm, 30mm, 32mm , 36mm, & 40mm. FORMULA TO CALCULATE WEIGHT OF STEEL BARS: For kg/m : W = D²L/162 For kg/foot : W = D²L/533        Where, D = Diameter of steel bar in mm                     L = Length of steel bar in m                    W = Weight of steel bar in kg If we put 1m length for each diameter of steel bar in the formula then we will get the unit weight. For kg/m : W = D²L/162 6mm Φ bar = 6²*1/162 = 0.222kg/m 8mm Φ bar = 8²*1/162 = 0.395kg/m 10mm Φ bar = 10²*1/162 = 0.617kg/m 12mm Φ bar = 12²*1/162 = 0.89kg/m 16mm Φ bar = 16²*1/162 = 1.58kg/m 20mm Φ bar = 20²*1/162 = 2.47kg/m 25mm Φ bar = 25²*1/162 = 3.86kg/m 32mm Φ bar = 25²*1/162 = 6.32kg/m For kg/foot : W = D²L/533 6mm Φ bar = 6²*1/533 = 0.067kg/ft 8mm Φ bar = 8²*1/533 = 0.120kg/ft 10mm Φ bar = 10²*1/533 = 0.188 kg/ft 12
