GATE ME 1998

MCQ (Single Correct Answer)

-0.3

Bolts in the flanged end of pressure vessel are usually pre- tensioned. Indicate which of the following statements is not true

Pre- tensioning helps to seal the pressure vessel

Pre- tensioning increase the fatigue life of the bolts

Pre- tensioning reduces the maximum tensile stress in the bolts

Pre- tensioning helps to reduce the effect of pressure pulsations in the pressure vessels

shear force and bending moment

axial force

torsion

torsion and bending moment

GATE ME 1987

MCQ (Single Correct Answer)

-0.3

Weldments in fabricated steel beams are designed for

bending stresses at the flange

shear stresses in transverse plane

combination of bending and shear

none of these because in fabricated beams welds do not get stressed.
