In this short problem we investigate the tensions and compressions
in a framework made from springs and ropes.
Derive Euler's buckling formula from first principles.
Which parts of these framework bridges are in tension and which parts are in compression?
Gravity on the Moon is about 1/6th that on the Earth. A
pole-vaulter 2 metres tall can clear a 5 metres pole on the Earth.
How high a pole could he clear on the Moon?
A cone is glued to a hemisphere. When you place it on a table in
what position does it come to rest?
Balancing interactivity with springs and weights.
