Question

1. a material is expected to fail at 50,000 psi. a safety factor of 2 is to be used. what is the allowable stress?

Explanation:

Step1: Recall the formula for allowable stress

Allowable stress = Failure stress / Safety factor

Step2: Substitute the given values

Failure stress = 50000 psi, Safety factor = 2. So, Allowable stress = $\frac{50000}{2}$

Step3: Calculate the result

$\frac{50000}{2}=25000$ psi

Answer:

25000 psi
