Question

12.3-6. The simply supported beam has 4 external loads plus an "additional load" when singularity i.e. discontinuity) function is used - two of them (couple moment & roller reaction) do not play a role because they are located at the right end of the beam. Determine the numerical value for the coefficient C (including appropriate + or - sigo), location a, and polynomial order p for the contribution to moment written in terms of singularity (and/or regular) function for: a) pin joint reaction, b) original rectangular distributed load, and c) "additional load." You may assume that the coefficient C takes on whatever units necessary for the singularity function to be of the form CX-a (or regular function of the form Cx'). Pin joint 1 = coefficient C for pin joint reaction Original rectangular load 200 kN/m =location a for pin joint reaction (IF singularity function] 80 kN-m -polynomial order P for pin joint reaction = Enter letter S or R 7777777 [S=singularity or R regular function] 8 m 8 m = coefficient C associated with original rectangular distributed load Additional load is what? =location a associated with original rectangular distributed load [IF singularity function] = polynomial order P associated with original rectangular distributed load = Enter letter S or R [S=singularity or R regular function] = coefficient C for additional load =location a for additional load [IF singularity function] -polynomial order for additional load = Enter letter Sor R
