Thanks rb1957, the topple was initiated when a vehicle carrying these cylinders/bundles manoeuvred around a corner. So it's difficult to predict the actual initial force, i have considered assuming some value of g-force in the horizontal plane. I understand that whatever value i come out with...

Thanks, the real world scenario was that a cylinder bundle toppled and struck a single gas cylinder. I want to estimate the likely energy of the collision and compare it to the energy required to fracture the cylinder material. I have modelled the system as an inverted pendulum and assumed...

Hi JStephen, Thanks, thinking about the moment of inertia is why I've simplified it as a cuboid. In reality it's frame assembly with many members, so it got me thinking would i even need to consider inertia before spending the time figuring it out. I will look further into rotational energy...

Hi MJCronin, It is a real problem, albeit heavily simplified. I just want to know if my thought process is correct or if there's any published work on this because i cant find much. thanks, Nick

*Correction ∆h should be the difference in heights of the COM (not the corner as shown in the picture)

I want to calculate the impact energy of a toppling cuboid striking a vertical surface. Once the cuboid is brought just past it's toppling point the only force acting will be it's weight. Will the energy of the impact be equal to the transfer of gravitational potential energy to kinetic energy...
