Question

Q1: Assume that you are working as a mechanical engineer in a steel fabricating company, Your section
head is asking you to calculate shear force and bending moment for fixing a machine which is having a
cantilever beam of length 23000 mm carries a point load of 290 N, 0.175 kN, 190 N acting at a distance of
4.5 m, 9000 mm, 1800 cm from right free end. Also your section head wants you to draw the shear force
and bending moment diagram for the beam. Mention at which section the shear force and bending moment
will have their maximum and minimum value, Jusify your answers.

Answer 1

Conclusion, Massimum Sheer force wir ke at the section DE Which is 655N and minimum shear forse wie be at section AB whim is Zero, at section AB there is noforce at the beam, Masimum Bending moment wie be at Saudition point & Wheen is 87650m. . moment occursat fisied end abi in Cantilever been maneimum bending and always Meninum Bending moment will be at Section AB which is zero Because no force, do No shear force s No Bending moment.
