Launch the simulation, then answer the question. Launch the simulation from this image. Part A Which of the following is true regarding the deformation of a beam subjected to both bending and shear? Which of the following is true regarding the deformation of a beam subjected to both bending and shear? The shear-strain distribution over the cross section is uniform. The longitudinal shear stress along the length of the beam is zero. The section remains a plane. None of the options are correct. Request Answer Provide Feedback

Solution

answer)

none of the options are correct.

explanation:

from the assumptions of bending stress distribution,

1. plain section before bending remains plane after bending, it means the longitudinal strain vary linearly from zero at neutral axis to maximum at the surface is only possible in pure bending where shear force is zero(but the beam is subjected to both bending and shear so false)

2. strain varies linearly.
