What is the elastic region in a material's stress-strain curve?
The region where the material deforms permanently
The region where the material returns to its original shape
The region where the material breaks
The region where the material becomes plastic
What is the behavior of materials at the yield point?
They return to their original shape.
They begin to deform plastically.
They become more elastic.
They become more rigid.
What is the role of stress distribution in a bolt?
It helps the bolt to compress.
It indicates potential failure points.
It makes the bolt more elastic.
It reduces the bolt's strength.
How is torque measured?
By dividing force by distance
By multiplying force by distance
By adding force and distance
By subtracting distance from force
Which unit is considered the 'base' unit for torque in the Imperial system?
Newton metre
Pound force foot

Ounce force inch
Which of the following is NOT a method for determining tightening torque experimentally?
Measurement of bolt extension
Use of a load cell
Strain gauges
Visual inspection
What is the purpose of gradually tightening fasteners to their full load torque or extension?
To ensure even pull-down and joint compression
To increase the speed of assembly
To reduce the number of bolts needed
