2. consider a linear elastic beam under bending loads. the total length isl and themoment of inertia is 2aiy da=∫∫. the beam has a linear strain-stress relationshipeσε=. (i) we know that the relationship between the axial norm strain ε and the transverse displacement v is 22dvydxε= −derive the strain energy ()u uv= of the beam. (ii) we know that the relationship between the axial norm

A)-in the process of engineering design, explain the contribution of material selection. b)- explain the procedure of synthesis as is employed in engineering design. c)- is there any relationship between ergonomics and engineering design? explain. d)- safety consideration in engineering design includes human, product and the enviroment . explain how safety will be incorporated into the design?
