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)
Vehicle Weight (W) 50 tons
Bridge Load Limit (L) 100 tons
Bridge Structural Status:
The statement 50 ≤ 100 is TRUE. The bridge struts hold the vehicle load safely.

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
Left Load Weight (A) 6 blocks
Select Operator
Right Load Weight (B) 4 blocks
Balance Evaluation:
Left side has 6 blocks, Right side has 4 blocks. Selecting operator > satisfies the comparison layout!
