How does the thrust rating of a push rod/linear actuator (I've seen it in both kg and N) relate to the amount of weight it can move?
I'm working on a custom RC project, and I'm needing to move a lever with a "weight" of 5 lbs. 5 lbs is required to actuate the lever, and I need to push it 5 mm. Gravity does not affect the ...

In a lead screw mechanism with a fixed travelling nut, will the screw and its driving mechanism move instead?
https://www.youtube.com/shorts/tUkkOStjz8o
Imagine this but upside down.
Since the platform bolted to the travelling nuts will be pressed against the ground and will have nowhere to go, I reckon the ...

Method to achieve a constant force no matter the actual velocity when under load
So, this might be a somewhat strange need, as I don't seem to see many resources on this. I'm trying to create a device where I can set an amount of force for it to generate, and when it would behave ...

Reciprocating motion in alternating tracks
I’m trying to find a solution for a simple feeder mechanism where a spring-loaded ”piston” gets pushed in a linear motion, and then on the way back it switches to parallel track, enabling it to be ...

What motors would be suitable for linear actuation in 1-2mm footprint?
I need to control simple braille (text for blind people) array with tiny rods. I don't necessarily have to control the precise location. A linear actuator with on/off states would be enough. However, ...

Using a Lead Screw To Create a Two Stage Clamping System
I want to use a motor to drive a lead screw that first brings down a platform that locks into place and then controls a secondary platform to apply pressure but using only a single motor.
As an ...

Is there a rotational-to-linear machine that doesn't allow the slider to impart torque while _between_ extremes?
Consider a machine for converting rotational motion to rectilinear translation, such as a crank slider or scotch yoke.
When the slider is at either of its two translational extremes (where the crank ...

Rotation of point in 3D space
I want to rotate a point (3,4,5) by an angle 45 degrees(0.785398 rad) in 3D space. I have used the standard DCM matrix in the order Rx, Ry and Rz.
Where,
$\theta = 0.785398 [rad]$
$$ Rx= \begin{...

Driving an air cylinder with ignited hydrogen/oxygen gas mixture from fuel cell?
Summary:
I need to build a linear actuator that has a very fast actuating speed but fits in a very small space.
My Question/Idea:
Electric gearmotors, c02, and air pressure, are all ideas that come to ...
