Tensile Test

Maximum stress in engineering stress-strain diagram is called

• Yield strength

• Breaking strength

• Tensile strength

• Young's Modulus

Which one is the measure of plastic deformation?

• Hardness

• Strength

• Stiffness

• % elongation

During Tensile Test experiment both upper cross head and lower cross head moves in opposite direction

• True

• False

Extensometer is

• used to measure applied load on the sample

• electronic sensor to measure elongation

• mechanical sensor to measure elongation

• A tool used to fix the sample between the cross head

Resilience of a material can be calculated by measuring

• the slope of the stress strain diagram at origin

• the slope of the stress strain diagram at the elastic region

• the slope of the stress strain diagram at yield point

• area under the stress strain diagram upto yield point

true strain is more than engineering strain.

• True

• False

In case of Cast Iron sample, fracture in tensile test occurs

• in the plane at 45 degree with axis

• in the plane at 0 degree with axis

• cup and cone type

Which of the following is true?

• ductility is related to tensile force

• malleability is related to compressive force

• malleability is a measure of , how long we can draw a sample

• ductility is a measure of how thin we can make a sample by compressing it

UTM is used to

• Tensile Test

• Compressive Test

• Bending Test

• Fatigue Test

Tensile strength of CI is more than Compressive Strength of it.

• True

• False
