Unformatted text preview: Page 2 3-The nylon cord has an original length L and is tied to a fixed 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 D, . If the cord was originally unstrained when it was at C, determine the normal strain when the rollers move to D. Show that if the displacements are small, then 4-The material distorts into the dashed position shown. Determine (a) the average normal strains and the shear strain at A, and (b) the average normal strain along line BE....
