This calculator will determine the stress, deflections, area moment of inertia, and section modulus for a Beam Supported on Both Ends and loading at any location.

 Design Variables Modulus of Elasticity lbs/in2 (N/mm2) E = Moment of Inertia in4 (mm4) I = Load lbs (N) W = Distance in. (mm) x = Distance in. (mm) a = Distance in. (mm) b = Distance in. (mm) x = Distance in. (mm) v = Length in. (mm) l = Distance to neutral axis/plane in. (mm) z = Results Stress between load and "a" load point lbs/in2 (N/mm2) s = Stress between load and "b" load point lbs/in2 (N/mm2) s = Stress at load application lbs/in2 (N/mm2) s = Deflection between load and "a" point in. (mm) y = Deflection between load and "b" point in. (mm) y = Maximum Deflection at Load in. (mm) y = Section Modulus in3 (mm3) Z =
