What is required to relate the stress distribution to the resultant bending moment?
Expert Solution
Step 1
The restoring force per unit area which is equal in magnitude of the applied force but in opposite direction is known as stress.
The distribution of stress in a curved flexural member is expressed as
now the sum of the normal force acting is equal to zero that is
this equation indicates that the neutral axis and centroidal axis doesn't coincide
