Final answer:
The tension in the material when the area is 1.5 mm² and the stress is 2 x 10^7 N/m² is calculated to be 30 Newtons.
Step-by-step explanation:
The student is asking about calculating tension in a material given the stress and the cross-sectional area. The formula to find tension (T) is:
T = stress × area
We are given that the stress is 2 x 10^7 N/m², and the area is 1.5 mm². First, we need to convert the area from mm² to m²:
1.5 mm² = 1.5 x 10^-6 m²
Now, we can calculate the tension as follows:
T = (2 x 10^7 N/m²) × (1.5 x 10^-6 m²)
T = 30 N
Therefore, the tension in the material with a cross-sectional area of 1.5 mm² and stress of 2 x 10^7 N/m² is 30 Newtons.
