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. Joint D is elongated downwards by delta subscript 3 which equals 5.14 millimeters.

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

... to the rigid bar deflection at joint C.

vD=vC+δ3    =3.24 mm+5.14 mm    =8.38 mm
