Problem no: 1 Find the Slope at the supports and deflection at the center of the beam shown in fig.  The conjugate beam is also simply supported beam with M/EI diagram as a Loading diagram. There fore the Reactions at supports,  Ra and Rb = 1/EI xTotal load on conjugate beam/2  Ra = Rb = (2x4 + 2x2/2)/ 2EI = 5/EI  The Shear Force at Supports = Ra and Rb  There fore the Slope at the supports = 5 /EI   The B.M. at the Mid point in the conjugate beam = Deflection at mid point.  EI x Mc = 5x2.5 - 1/2x2x1x(2+1/3) - 2x2x1 = 6.167 yc = 6.167/EI  Problem no: 2 Determine the Slope and Deflection at free end of the cantilever beam as shown fig. S olution: The conjugate beam of the actual beam is shown in Figure 4.8(b).  A linearly varying distributed upward  elastic load  with intensity equal to zero at  A, and equal to  PL/EI  at  B.  The free-body diagram for the conj...

BASIC DRAWING COMMANDS FOR AUTOCAD Measuring Commands GRID:  Displays a grid of dots at a desired spacing on the screen. Command:  GRID (enter) On/Off/Tick spacing(x)/Aspect:  (enter value) (enter) SNAP:  Specifies a “round off” interval so that points entered with the mouse can be locked into                          alignment with the grid spacing. Command:  SNAP (enter) On/Off/Value/Aspect/Rotate/Style:  (enter value) (enter) Basic Draw Commands CIRCLE:  Draws circles of any size. Command:  Circle (enter) 3P/2P/TTR/ :  (pick a center point) Diameter or :  (Pick a point on the circle) LINE:  Draws straight lines between two points Command:  LINE (enter) From Point:  (pick a point using the mouse) To Point:  (Pick a point using the mouse) To Point:  (Press return to end the command) ARC:  D...
