Both calculators run independently — change the inputs on either side to compare results.

Slope Stability Calculator

Compute the factor of safety against sliding failure on an infinite slope using soil strength and groundwater parameters. Used by geotechnical engineers assessing embankments, hillside cuts, and natural slopes.

Beam Deflection Calculator

Compute the maximum mid-span deflection of a simply supported beam under a uniformly distributed load (UDL) using δ = 5wL⁴ / (384EI). The standard structural-design check for serviceability — verifies whether a beam stays within deflection limits like L/250 or L/360 under service loads.
