Reactions, loads, S and M diagrams and the exam twists — every topic on one page, with a worked example and traps.

Every page: a short answer, why it works, one solved example and the pitfalls. Every number was checked against the BST engine.

Reactions and loads

Reactions, a distributed load, a triangular load and an inclined force.

  1. 01Reactions in a beamTwo moment equations — and you are done
  2. 02Uniformly distributed loadOne force at the middle — for the reactions only
  3. 03Triangular loadHalf the rectangle, at a third from the high side
  4. 04Inclined force on a beamResolve it before anything else

S and M diagrams

The shear force and the moment along the beam, by the area method.

  1. 05S diagram — shear forceFrom left to right, jump after jump
  2. 06M diagram — bending momentThe area method, and Mmax at Z

Twists in the exam

A concentrated moment, a cantilever and a fixed support — what costs points.

  1. 07Concentrated moment on a beamS does not move, M jumps
  2. 08Beam with a cantileverNegative M over the support — and Mmin
  3. 09Beam with a fixed supportThree reactions, and M starts at RMA
