Q1/ A glued lap splice is to be made in a (10 mm * 20 mm) rectangular member at angle as
shown in the figure below. Assuming that the shear strength of the glued joint controls the
design. What axial force P can be applied to the member? Assume the shear strength of the
glued joint to be 10 MPa.
a=20°
Q2/ IF a load of 1 Kip is applied to a rigid bar suspended by three wires as shown in the
figure below, what force will be resisted by each wire? the outside wires are aluminum ( E
=10' psi ) the inside wire is steel (E = 30 * 10° psi) Initially , there is no slack in the wire.
