Question

a structural rod has a radius of 5 mm and a length of 1 m.A 10*10⁵ N force stretches it's along it's length.calculate stress elongation and force on the rod.[given, Yfor steel = 2*10¹¹ Nm⁻²]​

Answer 1

To calculate the stress, elongation, and force on the rod, use the formulas related to stress and Young's modulus.

Step-by-step explanation:

To calculate the stress, elongation, and force on the rod, we can use the formulas related to stress and Young's modulus. Stress is calculated by dividing the force by the cross-sectional area of the rod, elongation is calculated using the formula (force x length) / (cross-sectional area x Young's modulus), and force can be calculated by multiplying the stress by the cross-sectional area. In this case, the force is given as 10*10⁵ N and the radius of the rod is 5 mm, so the cross-sectional area can be calculated using the formula pi x (radius)^2. With Young's modulus given as 2*10¹¹ Nm⁻², we can calculate the stress, elongation, and force on the rod.
