A stress of 210 MPa is applied to a low-carbon steel with an elastic modulus of 211 GPa. After the stress is applied and then re
moved, we note that the permanent strain at 0 stress is 0.1. What was the total strain when the stress was equal to 210 MPa

Answer:
a = 3.27 m/s²
T = 275 N
Explanation:
Given that:
Mass m₁ = 42.p0 kg
Mass m₂ = 21.0 kg
Consider both masses to be in a whole system, then:
The acceleration can be determined as:
Making acceleration the subject in the above formula;
a = 3.27 m/s²
in the string, the tension is calculated using the formula:
T = 274.68 N
T ≅ 275 N
