Instruction for Calculator for Bending moment and shear force of Overhanging beam

Instructions for using Overhanging Beam Calculator

(i). Sign Convention
(a)
The loads acting upward are considered as positive while the downward loads are taken as negative. Sagging bending moment is taken as positive and hogging as negative.

(b)The clock-wise rotation and moments are negative and anticlock-wise as positive.

(ii) All the distances should be measured with reference to the origin of axes which is taken at the extreme left end of the beam. All the distances should be entered in meter. d1 and d3 are the unsupported lengths of the beam on the left and right side of the supports at A and B. d2 is the length of beam which is supported.

(iii)The point load (P) is to be entered in kN and UDL in kN/m. It will give the values of support reactions in kN, Bending Moment in kNm and Shear Force in kN.

(iv) You can also quickly get the B.M. values at different sections of the beam, just by changing the position of section "x".

(v) In case of more than one load, take the sum of the results of all the cases (apply principle of superposition). Calculated values can be used to plot the bending moment diagram.

(vi) This calculator can also be used to find the ordinates of influence line diagram for structures..

You can select from the load cases given below to start calculation.
