All:
I need to build/buy a power surge protector for a 220V-60A
Double Oven. Or, Plan B, something inside the oven to protect the control/display circuit boards at a lower
voltage/current rating.
Background:
My elderly mother lives alone in rural area prone to
power failures. The last one...
Gentlemen:
Is there a useful relationship between the hardness
of an aluminum alloy and its tensile strength? Is
there a general rule of thumb that can be applied?
If so, does this relationship apply only within an
alloy series or across some or all series?
Thanks....

Gentlemen:
This is not my field, but I have had to pick up
some of the load....
I have a brushed DC gearmotor, 300 in-lb torque, with output of 8 RPM. If the speed is reduced thru a PWM controler to 1 RPM, will there be any torque left
for the load? Any guess as to how much?
Thanks in...
Gentlemen:
I need help finding the shear strength of
416 SST @36 RC. Can anyone help? Hopefully
with a quotable reference...Thanks

Gentlemen:
I have been through 20+ of my engineering books and a web search and I cannot find anything regarding torque or
power loss through a u-joint. Also, I am trying to
calculate the radial load for a bearing adjacent to
the u-joint. Can anyone direct me to a source of info
or provide...
Gentlemen:
Is there a simple, shop based, test that can be used to
distinguish martinsitic SST (400 series) from CRS/Drill Rod?
Hopefully something on the order of grinding wheel sparks,
etc...
Thanks

Greetings Gentlemen:
I hope you can point me in the right direction. I am trying to estimate the residual stress in a weld. I have a machine with a central column which is a 9 C 20.0 channel welded to a 1/2 in X 18 in SQ base plate. The base plate is welded to the end of the channel all...
Gentlemen:
I am working on a project that has a proprietary motor
control board that is used to control 6 DC motors on a medical
device. During development and in the field there have
been situations where the motors have been connected
wrong, wired wrong, accidental shorts etc which has
fried...
Gentlemen:
One of several solutions to an electronics packaging
design would involve spotwelding an SST housing to CRS internal brackets, shields, etc. None of
my metallurgy books address this situation so I would
presume it to be problematic. This design is for a
medical device in an OR...
Is there an adapter/cable available that I can use
to test a drive outside of my computer; possibly
through a USB port? Or is the only alternative to
pull the cover and plug into the ribbon cable??
It is well known that 300 Series Stainless can
become magnetic by cold working. What is the
mechanism? How can a macro type operation
affect what is a nuclear property? I can't find
this in any of my metallurgy books...Thanks
