Question
3. A force P is applied to the rigid lever arm ABC as shown. The arm rotates counterclockwise about pin
A through an angle of 0.06. Calculate the normal strain developed in wire BD.
Answer:
0.0014 mm/mm
300 mm
400 mm-
4. The control linkage of an airplane consists of a rigid member DBC and a flexible cable AB. A force P is
applied to the end D of the member and causes it to rotate by 8-0.35°. The cable is assumed to be
originally unstretched. Determine the strain developed in the cable.
Answer: A = 0.00282 mm/mm
