Hi
No its not a homework problem, rather a curiosity in suction cup design and load capacity.
This arose while using suction cup phone mounts or clothes line as well as with respect to nerf arrows.
Below is a diagram of the suction cup with a suspended load.
Applying force equilibrium, we get...
I'm looking for means of calculating load carrying capacity of a vertically mounted suction cup.
Suction Cup effective diameter = 90mm
Mounted on a vertical glass surface
Pressure inside the suction cup = 0.75bar
Pressure difference = 0.25bar
Weight is suspended from a rod attached in the centre...
