PROBLEM 10.21 For the linkage shown, determine the force P required for equilibrium when 18 in., a = 240 lb in., M = and 30 . θ = ° SOLUTION Consider a virtual counterclockwise rotation δφ of link AB . Then B a δ = Note that cos BB y δθ = cos a θδφ = If the incline were removed, point C would move down C y as a result of the virtual rotation, where cos CB yy a φ == For the roller to remain on the incline, the vertical link BC would then have to rotate counterclockwise. Thus,
