Structures are drawn by dragging on a canvas, and the results sit beside the drawing rather than under it. Neither works on a screen this narrow, so rather than give you a cramped version of both, it asks for a wider window.
Open it on a laptop or desktop, at 1024 pixels wide or more.
Draw the structure, press Calculate, and read the answers. There is no beam mode or truss mode to choose between — a member hinged at both ends is a truss member, and whatever you draw is what gets solved. Report (Ctrl+P) gathers the drawing and the results onto one sheet to print or save as PDF. Free with a Google sign-in for models of up to 15 members; Membership adds combinations, the full report, Word export and saving to the account. For education and preliminary checking only.
