Linkage multiplication mechanism 1


Move blue T-bar to enter positive number x Move yellow slider to enter positive number y Orange T-bar shows z = x*y At point C there are 3 pink sliders (sliding in slots of violet, orange and blue bars respectively) connected together by revolution joints. The screw lead must be large enough to avoid self-locking. The video shows operation 40*50 = 2000 and then 50*80 = 4000. The mechanism works on congurent triangles rule. From triangles OBC and OAD:
OB/OD = BC/AD OB = x ; AD = y ; BC = z ; OD = k = 100 mm (constant) then z = (xy)/k
For the X and Y scale, 1 mm corresponds 1 unit. For the Z scale, 1 mm corresponds 100 units. The division x = z/y can be performed on this mechanism: enter z and y and get x.
