Mechanical Expressions

Explore Statics Examples

Add force elements to your model, and you can measure resultant forces and torques.

Force and Spring Equilibrium

Force and Spring Equilibrium

An expression is derived which, when solved will yield the equilibrium position of a spring loaded mechanism under an applied force.

Crank Slider Torque

Crank Slider Torque

An app which derives the torque in a crank slider mechanism due to a given applied force.

forces in a simple structure

Forces in a Simple Structure

We show how body forces are computed as reactions in constraints. We also show how to compute reactions at pins.
