Analyze bending stress and shear force in simply supported and cantilever beams by applying loads and cross-section properties in this civil engineering tool.
Engineering
Control Systems — Feedback Loop Design
Design and analyze feedback control systems by placing poles and zeros, plotting Bode and root-locus diagrams, and testing step responses interactively.
Engineering
DC Motor Simulator — Torque & Speed Curves
Simulate DC motor behavior by adjusting voltage, load torque, and winding parameters to explore torque-speed characteristics and transient response.
Engineering
Electrical Circuit Simulator — AC & DC
Build and simulate DC and AC electrical circuits with resistors, capacitors, inductors, and voltage sources to measure current, voltage, and power.
