Normal Stress

Fig shows a bar of uniform cross section of area s . Equal and opposite tensile forces are applied at the ends of the bar. Each force has a magnitude F . ABCD is a plane trough the bar and inclined at angle theta with the perpendicular to the length of the bar. Normal stress at the plane which is inclined with the plane perpendicular to the length of the bar is -

Two bars A and B are stuck using an adhesive. The contact surface of the bars make an angle q with the length. Area of cross section of each bar is S_(0) . It is known that the adhesive yields if normal stress at the contact surface exceeds sigma_(0) . Find the maximum pulling force F that can be applied without detaching the bars.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 : Ratio of normal stress to volumetric strain is bulk modulus of given gas. STATEMENT-2 : Compressibility is the reciprocal of bulk modulus.
