To determine the reaction of the pedestal, RA and RB other than by way count as above can also be determined by means of painting which can simultaneously determine the moment diagram and shear force diagrams
is as follows: Do the following:
– Determine the length scale, for example 1 m # 1cm
– Determine the style scale, for example, 100 N # 1 cm
– Create an image Stem AB burdened by force F and riveted on two pedestal in accordance with the length scale and the scale of his style.
– Create a painting pole namely: move the force F at point P on the right pedestal picture.
– Determine the polar point O with a free position / Random
– Draw a line from ttik pole O to the point P and the ends of the force F, so that in can line (1) and (2).
– Extend the line style of the pedestal A, B and the pedestal of the force F which are at the point C to the bottom.
– Create parallel lines (1) cut the work force line RA at the point Q and the line of action force F at the point R.
– Create parallel lines (2) cutting R and RB work line at the point S.
– Create a line as a cover from point Q to point S so that in can line (3)
– Create a field bounded by points Q, R and S, the shaded areas of the call with the field of the moment or the moment diagram.
– To determine the amount of RA and RB, continue to create parallel lines (3) cut the polar point O and the force F at point P ‘. so that in can be RA and RB.
6:14 image moments and shear force diagrams
– Move RA and RB A pedestal to pedestal to B using the term.
– Multiply the length RA and RB with scale style so can the RA in the unit of force.
– To determine the field / shear force diagrams are as follows:
– Create a horizontal line at the line of force at the point U RA and RB work cut line at point Z
– Move the RA to run from point U to the top with the tip at point V.
– Create a horizontal line to cut the line of action force F at point W.
– Move F to W with its end point at point X.
– Create a horizontal line from the tip force F or the point X to the right to cut the line work force at point Y RB.
– Move the RB to the point Y by the end of the RB at point Z, in order to get the field of shear force or shear force diagrams.
– Create a style shading limited by style or point of U, V, W, X, Y and Z. The field is a field or a shear force diagrams.
