Physics 2014 JAMB Past Questions - Question 16: A force of 500N is applied to a steel wire of cross sectional area 0.2m-² the tensile stress iis
Choose the correct answers from the options given.
A:
B:
C:
D:
Correct Answer
C
Explanation
To calculate the tensile stress, we can use the formula:
Stress = Force / Area
Given that the force applied is 500 N and the cross-sectional area is 0.2 m², we can substitute these values into the formula:
Stress = 500 N / 0.2 m²
Calculating this, we find:
Stress = 2500 N/m²
Therefore, the tensile stress on the steel wire is 2500 N/m².
