Document Summary
The output angle in a four bar mechanism is at its extremes when links 2 and 3 are collinear. Solving the linear equations in (1) and (2) we obtain. To draw the mechanism to scale we would require the length of link 1 i. e. o2o4 . From o4b b (isosceles triangle, hence bisector is perpendicular) l2 = 63. 5mm, l3 = 165. 5mm. B =l3 + l2 = 229 (1) (2) Consider o2b b , using cosine rule we have. The transmission angle is extremum when links 1 and 2 are collinear. The maximum transmission angle can be obtained by applying the cosine rule to amaxbmaxo4 , Similarly the minimum transmission angle can be obtained by applying the cosine to. The vector loop equation for the above four bar mechanism is. This can be resolved into components with the coordinate axis fixed at.
