The nylon cord has an original length L and is tied to a bolt at A and a roller at B. If a force P is applied to the roller, determine the normal strain in the cord when the roller is at C, and at D. If the cord is originally unstrained when it is at C, determine the normal strain ε'_Dwhen the roller moves to D. Show that if the displacements Δ­_Cand Δ_­Dare small, then ε'_D = ε'_D€“ ε'_C.
