600 mm B 800 mm P Part of a control linkage for an airplane consists of a rigid member CB and a flexible cable AB. If a force is applied to the end B of the member and causes a normal strain in the cable of 0.004 mm/mm, determine the displacement of point B. Originally the cable is unstretched. Hint: After determining the stretched length of AB, use law of cosines to determine 0; then use 0 to determine the arc length over which point B displaces.
