Find minimum force to move block

[QUOTE="Simon Bridge, post: 4525826, member: 367532"] I would try the work-energy relation and conservation of energy. Otherwise you'd have to draw the free body diagrams. The wrinkle I see is that block A also gets pressed against the side of the whatsits that constrains it to the vertical - in proportion to the applied force. (The applied force ends up creating a couple with the reaction forces in the constraint - I suspect that this is "overthinking" the problem at the level it is presented.) You should get a number of equations where it appears that things have a circular dependence - and you can cancel terms. [/QUOTE]
