Question

Compute the shear stress in the material if a force of 2230 lb is applied through the punch. The thickness of the material is 0.03 in.

a. 74,333.33 lb/in²
b. 1,179 lb/in²
c. 74,100 lb/in²
d. 2,230 lb/in²

Answer 1

Shear stress in the material can be calculated using the formula: Shear stress = Force / Cross-sectional area. Substituting the given values, the shear stress is approximately 74,333.33 lb/in².

Step-by-step explanation:

The shear stress can be calculated using the formula:

Shear stress = Force / Cross-sectional area

Given that the force applied through the punch is 2230 lb and the thickness of the material is 0.03 in, we can calculate the cross-sectional area:

Cross-sectional area = thickness

Substituting the values into the formula:

Shear stress = 2230 lb / 0.03 in² = 74,333.33 lb/in²

Therefore, the shear stress in the material is approximately 74,333.33 lb/in².
