The bridge truss shown in the figure is to be subjected by uniform load of 10 kN/m and a point load of 30 kN, both are moving across the bottom chord
Calculate the following:
1. The maximum axial load on member JK.
|A. 64.59 kN
||C. -64.59 kN
|B. -63.51 kN
||D. 63.51 kN
2. The maximum axial load on member BC.
|A. 47.63 kN
||C. -47.63 kN
|B. -74.88 kN
||D. 74.88 kN
3. The maximum compression force and maximum tension force on member CG.
|A. -48.11 kN and 16.36 kN
|B. Compression = 0; Tension = 16.36 kN
|C. -16.36 kN and 48.11 kN
|D. Compression = 48.11 kN; Tension = 0
