Rigid bar hanging from cables
Problem statement
Calculate the elongation of each cable and the vertical displacement of point C, where the load is applied. Consider bar ACB to be rigid (it does not bend). The cables are made of steel, with diameter Dc = 1.5 cm and E = 200 GPa.
Figure data: 2.0 m long cables at A and B; 20 kN load at C; AC = 3.0 m and CB = 2.0 m.
Concepts: cable elongation, vertical displacement, axial deformation, steel cables, rigid bar
