The force P applied at the handle of the rigid lever shown in Fig. 4 causes the lever to rotate clockwise about the pin E causing wires AB, CD and FG to elongate. If the normal strain of wire CD is 10-3 and the length of wire FG is 250 mm, determine the average normal strain in each wire and the angle of rotation of lever. All the wires are perpendicular to the lever arms at the points at which they are attached and are unstretched when section ACE of the lever is in the horizontal position.
