Inequalities & Balance Bridges
Understand variables bounded by inequalities. Explore load safety limits on bridges, physical see-saw scales, and directed interval number lines.

Load Limit safety Bridge
An inequality bounds variables within ranges. Here, the bridge can support a maximum safe load limit L. If vehicle weight W violates the constraint W ≤ L, the structure collapses!
Inequality Constraint
W ≤ L (50 ≤ 100)
Bridge Structural Status:
The statement 50 ≤ 100 is TRUE. The bridge struts hold the vehicle load safely.
Interactive Weight Balancer
See-Saw Balance Scale
Compare quantities A (left) and B (right) on a physical balance see-saw. Select the correct comparison operator to satisfy the structural balance layout.
Inequality Comparison
6 [ ? ] 4
Balance Evaluation:
Left side has 6 blocks, Right side has 4 blocks. Selecting operator > satisfies the comparison layout!
