- Calculate Load carrying capacity of vertically mounted suction cup

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 of the suction cup.

Rod length = 150mm

Need to calculate how much weight can be suspended before the suction cup pulls off the glass surface

Assume, coefficient of friction between suction cup and glass as 0.2
