INSTRUCTION: THE TEST SHOULD BE TAKEN FOR THE PRESCRIBE TIME.
. Tungsten inert gas welding
. Metal Inert gas welding
. Electro gas welding
Electro slag welding
. In the bottom
On the deck
It is found in the hull section
. On the forepart where the weight is less
. It is found in the hull section
Conducted prior to docking survey
. Become due every 4 years
. Conducted twice in any docking survey
. Done at the end of the docking survey

When there is longitudinal distortion
When simultaneous loading starts
When there is a constant varying loads
. when hogging is experienced
. U-weld
. Double V preparation
. Square-edge
. V-weld
. Pitching
. Rolling
. Heaving
Swaying
Ultrasonic inspection
Dye penetrants
Radiographic inspection
Visual examination
. Racking
. Pounding
. Sloshing
Panting
. By the effect of stress and strain as to fatigue
. By determining its total strain
By dividing the area of the material by its load
. By determining its load per unit area
Stress is directly proportional to strain
. Stress is indirectly proportional to strain
. Strain is indirectly proportional to stress
Stress directly proportional to the sectional area of the material
. Thermit welding
. Resistance welding
. Electric Arc welding
Gas welding
. A butt weld for
. A temporary weld
. A lap weld
. A flush weld
The area experiences too much panting in heavy weather
. It is because of the structure of the framing system
It is affected by too much rolling and pitching
It is where buoyancy is usually present
Tensile stress
. Bending moment
Shear forces
. Compressive
Total stress minus load
The opposite of stress
. The total deformation which the body experiences when subject to load
The upward and downward distortion forces
. Lighter than mild steel
. saves weight
Use on areas of high stress
. Saves cost
It allows a molten steel to solidify in a mould of a desired shape
. Method of shaping a metal by hammering
. It becomes more or less plastic
Metal becomes brittle
. hogging
Sagging
. pounding
. dynamic force
Heaving
. Pitching and heaving
Rolling
Surging and swaying
Its midship part is supported by buoyancy.
The buoyancy is more in the midship part.
. It creates weight equal to its buoyancy
. The buoyancy created is greater on the fore and aft part
. Twice every special survey
. Every year
Once every dry dockings
On any of the two dockings in a five-year period
