Edit: Never mind guys, figured it out. I needed to use s.equals :)
However, could someone explain to me why we can't use == on a technical level?
I'm curious to know on a technical level.

G'day guys
So I currently have a 2x 8" stoke 150lbs dynamic force actuators with a maximum current draw of 5A.
The exact one is the FA-PO-150-12-XX in the link below:

The load I have on it causes the actuators to draw almost its'...
Hi guys
I'm looking to calculate the static frictional force for a hinge
Below is a CAD image of the component I am testing.
I am thinking of attaching a hook onto the plate as shown below, and continuously add weights at the end of the hook until the hinge begins to move.
By multiplying...

Superman must stop a 120-km/hr train in 150 m to keep it from hitting a stalled car on the tracks. If the trains mass is 3.6 x 10^5 kg, how much force must he exert?
Vi = 33 m/s (120 km/h)
Vf = 0 m/s
Displacement (Xf - Xi) = 150 m
M = 3.6 x 10^5 kg

Hi everyone!
So I'm working on project where I have to design a hinge system for a hard lid that is fitted onto the back of a pickup truck.
In this system, I will be using 2x linear actuator(s) that will need to lift a total weight of roughly 95kg.
At the moment, I've got a selection of 600N...
