Question 1

What is a free body diagram solver?

Accepted Answer

A free body diagram solver lets you draw a structure with its supports, loads, and members, then computes the support reactions and internal forces by applying the equations of static equilibrium. StatIQ does this in the browser and shows each equation it solves.

Question 2

How do I solve a free body diagram?

Accepted Answer

Isolate the body, draw every external force and reaction acting on it, then apply the three planar equilibrium equations: the sum of forces in x is zero, the sum of forces in y is zero, and the sum of moments about any point is zero. StatIQ writes out ΣFx, ΣFy, and ΣM for your diagram and solves them step by step.

Question 3

How do you find support reactions?

Accepted Answer

Take moments about one support to eliminate its unknown reactions and solve for the other, then use the force-balance equations to back out the remaining reactions. StatIQ computes support reactions automatically and shows the moment and force equations behind each value.

Question 4

Is StatIQ free?

Accepted Answer

Yes. The free workspace lets you sketch and solve free body diagrams in your browser, with no time limit. Pro and Pro+ paid plans (with the full step-by-step Explain panel and AI Tutor) are temporarily unavailable while we finish setting up billing.

Question 5

Can StatIQ draw shear and moment diagrams?

Accepted Answer

Yes, for statically determinate beams StatIQ generates shear (V) and bending-moment (M) diagrams from the solved internal forces.
