yes . ' . +++ . You do NOT use "goggles" when arc-welding. You use a properface-shield (mine is the auto-darkening type), and you should notexpose any skin to the arc's intense UV radiation.
stress is directly proportional to strain up to the proportionallimit. Their ratio is young's modulus.
by welding we add some filler material which will fill the gapbetween the joint.
pump is used to handle liquid and compressor is used to handlegases. other difference include blade shape etc..
its better to see a video of welding to visualize it.
Generally gear pumps are used in hydraulic systems.
The button is used to allow the elevator doors to be open in a safe way and allow the building security etc. to know you are there and need rescue.
youngs modulus, modulus of rigidity, bulk modulus.
