CH 4: Deflection and Stiffness Stress analyses are done to ensure that machine elements will not fail due to stress levels exceeding the allowable values. However, since we are dealing with deformable bodies (not rigid), deflections should be considered also where they are in many cases more limiting than stresses. Take for example shafts where excessive deflection will interfere with the
