PROBLEM 10.2 Determine the vertical force P which must be applied at G to maintain the equilibrium of the linkage. SOLUTION Link ABC Link DEFG Assume clockwise δθ Then for point C ( ) 5 in. C x δ δθ = and for point D ( ) 5 in. D C x x δ δ δθ = = And for link DEFG 15 D x δ δφ = 5 15 δθ δφ = or 1 3 δφ δθ = Then 4 4 2 2 in. 3 G δ δφ δθ = = Now cos45 G G y δ δ = ° 4 2 cos45 3 δθ

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
