Must admit to being surprised at having created a problem which it appears that nobody has tackled before. As I say I can find nothing on the net. Even if I modify the question to say something like find what value of Fmove is required to move the pin upwards, in terms of theta and the friction...

Here's where I've got to. I've got as far as balancing the pin, then the wedge, and now I'm considering how the friction & perp forces between wall and pin should be accounted for. I've used a friction coefficient of 0.3, which has resulted in the "slip" beginning at ~17deg. When that...

One of the design constraints is that the force to activate the adaptor Fmove must be <= the force without the adapter Fdown. So I'm trying to deal only with the limit case where they are the same.

Hello folks. After a while lurking I've finally got a problem that I need some help with! 1. Homework Statement I'm designing an adaptor for a drinks optic and have translated one of the aspects of the design into the following problem. There is plenty of stuff on the net about simple...
