The linkage shown below has the known dimensions of a, b, cand d. It can be shown by geometry that the relationship between the angles a and B is (d-acos α-bcos β)2 + (a sin α + bsin β)2-C2-0 For a given value ofa, we can solve this transcendental equation for β by one ofthe root-finding methods we learned in the class. This had been done with a-0, 5, 10.30, the results being α (deg) 0 β (rad) 1.6595 |...
