Question

kinematics design of machinery

5. For each of these problems, find the range of values for the unknown link if the linkage will theoretically act as a (a) crank rocker mechanism (where link 1 rotates through 360); (b) drag link mechanism (double crank mechanism); (c) double-rocker mechanism (d) change-point mechanism; (f) triple-rocker mechanism. (Show your work to receive credit!) (i) Find Lo for L1 = 100 mm, L2 = 280 mm, L3 = 360 mm. (ii) Find Li for Lo = 40 mm, L2 = 60 mm, L3 = 40 mm. (iii)Find L2 for Lo = 50 mm, L1 = 200 mm, L3 = 250 mm. (iv) Find L3 for Lo = 120 mm, L-220 mm, L2 = 80 mm.

the shortest length have a lowest L and the longest length is the longest L the fixed length is the length that is between the shortest and longest .
