GATE 2018 Setl 2 marks A carpenter glues a pair of cylindrical wooden logs by bonding their end faces at an angle of 30degrees as shown in the figure. The glue used at the interface fails if Criterion 1: the maximum normal stress exceeds 2.5 MPa. Criterion 2: the maximum shear stress exceeds 1.5 MPa. Assume that the interface fails before the logs fail. When a uniform tensile stress of 4 MPa is applied, the interface
(A) fails only because of criterion 1 (B) fails only because of criterion 2 (C) fails because of both criteria 1 and 2 (D) does not fail Log 1 Log 2 axis 4 MPa 4 MPa 0-30
