Snow Ice Strength
Snow Ice Strength
(OP)
I am trying to figure out torque required to actuate a damper against ice-built up of 6 in on the blades.
Does anyone know where to find snow ice mechanical strength properties (tensile and shear strength) ?
Thanks,
StressStrain

I wouldn’t use the damper mechanism or any concentrated torque (or pry bar) to try to brake that ice loose. Whatever the ice strength, the damper blades or mechanism were not designed to do that. It may work, but it might damage the damper too. If you can, I would get up there with some heat, a heater and blower of some sort (a gas fired salamander?) to melt the ice off the blades from the inside. Then go outside and clear the ice away so you don’t bust up the bottom couple blades.
