Hi
I am looking for an appropriate materials to use for extruding into a "splice" shape that binds two aluminium profiles together. The only snag is the splice needs to be as fire resistant as possible. The design is similar to a thermal break splice used in external glazing frames...
We are trying to determine the current rating for a switch to operate a bank of flourescent lights.
Is there a simple formulae to calculate the operating and inrush current rating for the switch.
I am using a product called AnalysisGroup to determine deflection in a glass plate. The plate is one of a number of fully framed panels of glass held in an aluminium frame. This reults in the top and base having fixed edge supports and the two vertical edge supports being "spring" type supports...

I am trying to find out how to calulate the torque of minature stepper motor to operate louvered blinds (venetian blinds). The attached GIF shows the principle. Basically a rod has 3 control threads attached by winding the threads about 3 truns...

Sometime ago I found some software that checked deflection and bending stress in rectangular plates. Cannot find it now and so need to know if there is still such an animal out there ?
Requirmeents are for either 4 or 2 edge support, UDL, concentrated AND "line load" to calculate max...
