Assembly Deflection at D  
scene 7 of 7
The figure shows the deflections suffered by the rigid bar A C B. The deflection at joint A is v subscript A which equals 2.4 millimeters. The deflection at joint C is v subscript C which equals 3.24 millimeters and the deflection at joint B is v subscript B which equals 3.6 millimeters. The member between the points C and D is subjected to a load of 80 kilo newtons directed vertically downwards.

To determine the deflection of the assembly at joint D, add the deformation that occurs in rod (3)...
