hi,i have been doing experiments with individual pressure sensors, while attaching the sensor to my thumb, if i press my thumb onto a hard surface the pressure recorded is very high, but when i push my thumb onto a soft surface, like a sponge i have to press a lot harder to get a high pressure reading. Newtons third law states that every action force has an equal and opposite reaction force, even though i feel I am exerting more pressure when I am pushing the sponge, it does not show this on the pressure readings. Do the varying pressure readings have something to do with the elasticity of the sponge, thus increaseing surface area-pressure disribution is higher??
im a little lost as how to explain this well, sorry.
Any help would be great. Thanks
