Final answer:
Tension occurs when the tension force surpasses an object's ability to handle the lengthening force. It is a pulling force that acts along a stretched flexible connector. Tensile strain measures the deformation of an object under tensile stress.
Step-by-step explanation:
Tension occurs when the tension force in an object surpasses the object's ability to handle the lengthening force. Tension is a force along the length of a flexible medium, such as a rope or cable. It is a pulling force that acts along a stretched connector. Tensile strain measures the deformation of an object under tensile stress, which is the fractional change in length when an object experiences tension.
