Select all that apply

In the U.S. customary system, the units for shear and normal stress are (Select all that apply)
a. N/in²
b. Ibs/in²
c. psi
d. psi/in²
e. ksi/in²
f. ksi
g. pounds/in²

Answer 1

The correct U.S. customary units for shear and normal stress are Ibs/in², psi, ksi/in², and pounds/in². Therefore, options b (Ibs/in²), f (pounds/in²), and g (ksi/in²) are the correct answers.

Step-by-step explanation:

In the U.S. customary system, the units for shear stress and normal stress are used to define the ratio of force applied to a material's cross-sectional area.

The correct units from the options provided are b. Ibs/in², c. psi, e. ksi/in², and g. pounds/in². These abbreviations stand for 'pounds per square inch' and 'thousand pounds per square inch,' respectively. It's important to note that 'psi' is the most common term used, and it is equivalent to 'pounds per square inch.'

In comparison, one pascal (Pa), the SI unit, is equal to 1 newton per square meter (N/m²).

In the U.S. customary system, the units for shear and normal stress are pounds per square inch (psi) and pounds per square inch (lb/in²), respectively. Therefore, options b (Ibs/in²), f (pounds/in²), and g (ksi/in²) are the correct answers.
