Wooden strip models are great teaching aids Bill. I used them a lot to demonstrate the value of triangulation in stiffening structures. I suppose we ought to test the principle before trying to make one.
Can you alter the angles of the triangle? - yes
Can you alter the length of the sides? - yes
Will the sliders slide easiliy into their correct positon along the sides? - Ah! Friction might be a serious problem.
Will the springs pull the centre ring into the correct position? - that might need proving.
