An object that is deformed by a force and returns to its original form when the force is removed is exhibiting the property of elasticity.
A nylon string has a diameter of 2 mm, pulled by a force of 100 N. Determine the stress.
2.35 x 107 N/m2
3.15 x 107 N/m2
4.15 x 107 N/m2
A string has a diameter of 1 cm and the original length of 2 m. The string is pulled by a force of 200 N. Determine the change in length of the string. Young’s modulus of the string is 5 x 109 N/m2
Which of these factors does NOT affect the stress of a wire?
cross sectional area
What is the unit for stress?
Greater the angle of inclination of the stress strain curve less is the elasticity.
It is expressed as the ratio of the applied force divided by the resisting area.
The amount of deformation in the direction of the applied force divided by the initial length of the material.
What is zone A called?
What is point B called?
What kind of behavior is exhibited in point D?
What happens in point E?
In which point is the material permanently deformed but without fracturing?
