The beam ab is pin supported at a and supported by cable bc. Determine the resultant internal loads
A beam or frame is subjected to transverse loadings, and the three possible internal forces that are developed are the normal or axial force, the shearing force, and the bending moment.
How to determine the resultant internal loads?The resultant internal loads b = Nb =-2.16 kip, V b=0 M b=2.16 kip .ft
The resultant internal loads c=Nc = -4.32 kip, V c=0.54 kip M c=2.16 kip. ft
Solution: The beam ab is pin supported at A and supported by cable BC
The Weight of the beam AB is 120 I b/ft. The weight of the cable BC is 180 I b /ft.
find the loading at the center of beam AB (P ab)P ab= Weight of beam AB * Length of beam AB
substitute 120 I b /f t for the weight of beam AB and 12 ft for the length of beam AB
P ab=120*12 =1,440 I b convert the unit from I b to kip P ab=1,440 I b*1 kip/1,000 I b 1,44 kip
