I want to machine a small housing for electronics out of magnesium. (think portable computer, tablet pc or lightweight but rugged electronics) Usually I use 6061-T6 aluminum. 1) What magnesium alloys are commonly used in machining applications where availability, ability to coat for...

Does anyone know who might make a battery type connector to go on the outside of a sealed housing of a portable tablet PC in order to dock with a cradle? Need at least 8 spring loaded contacts, rated up to 7A. Would prefer one side of the connector to have flush contacts and this would go on...

Yes there was a right bracket missing. Here is the equation again: Integral(sqrt[((cosx)^2)+(x^2)]dx I'll use numerical integration but I was wondering if anyone out there knew of a definite integral for this one. Kilkenny

Can anyone integrate this? Integral(sqrt[((cosx)^2)+(x^2)]dx It is like the integral of a pythagorean formula composed of 2 functions of x. Thanks, kilkenny

Have you considered 3M VHB tape? Your posting says the width will be .8m to 1.2 mm, or 1.2 mm to 800 mm. That is a wide range. What temperature range?

Does anyone have or know where I can get a fatigue S-N curve for G-10 epoxy fiberglass, a material commonly used in circuit boards? Thanks,

Can anyone explain the meaning of "coefficient of rebound"? Steinberg, in "Vibration Analysis for Electronic Equipment" mentions it in the following equation: V=C*(2gH)^.5 where V=velocity change C=coefficient of rebound (1.0-2.0) g=acceleration of gravity H= drop height...

Description of assembly: I am bonding a polycarbonate overlay to a thick , smooth, acrylic sheet using a PSA (3M 468MP tape). The overlay is about 15" x 17". The acrylic has dozens of holes that are about 3/4" dia. for snap dome switches that the overlay covers. The outer edges...
