Question 2223 Deck Safety
70% to passTensile stress is a result of two forces acting in _______________.
A
opposite directions on the same line, tending to pull the material apart
B
opposite directions along parallel lines
C
opposite directions on the same line, tending to compress the object
D
the same direction along parallel lines
AI Explanation
The correct answer is A) opposite directions on the same line, tending to pull the material apart. Tensile stress is a type of stress that occurs when two forces act in opposite directions along the same line, causing the material to be pulled apart. This is the definition of tensile stress - forces acting to stretch or elongate the material. The other options are incorrect because: B) describes parallel forces, which do not create tensile stress; C) describes compressive stress, the opposite of tensile stress; and D) describes forces acting in the same direction, which also does not create tensile stress.
