Strain 2.6

Part of a control linkage for an airplane consists of a rigid member CBD and a flexible cable AB. If a force is applied to the end D of the member and causes it to rotate by , determine the normal strain in the cable. Originally the cable is unstretched.u = 0.3°. (P2.6)

Strain 2.7

The corners of the square plate are given the displacements indicated. Determine the shear strain along the edges of the plate at A and B. (P2.7)

Strain 2.8

The piece of rubber is originally rectangular. Determine the average shear strain at A if the corners B and D are subjected to the displacements that cause the rubber to distort as shown by the dashed lines. (P2.8) 

Strain 2.9

The force P applied at joint D of the square frame causes the frame to sway and form the dashed rhombus. Determine the average normal strain developed in wire AC. Assume the three rods are rigid. (P2.9)

Strain 2.10

The triangular plate ABC is deformed into the shape shown by the dashed lines. If at A, e_xy = 0.005P and Î_AC= 0.01 and g_xy = 0.05rad, determine the average normal strain along edge BC. (P2.10)
