Rock-Bolt Torque-Tension Curve Explorer (2D)

The 3D robotic bolter shows a twin-boom rig drilling and driving rock bolts to a target torque, but the actual physics of the joint happens out of sight, inside the resin-anchored hole. This 2D companion turns that single wrench stroke inside out: drag bolt diameter, anchor stiffness and target torque and watch the whole torque-vs-turning-angle curve build in real time as a bolt is driven — free-spinning thread engagement, elastic clamping-force buildup, a yield knee, and then either a safe stop inside the green window or a stripped thread if the target overshoots the joint's real capacity. A matching cross-section animation turns the same bolt so the curve and the physical install always agree.
