Chapter 24, Problem 38R

To determine

To explain:The material that should be considered if the product must be tear resistant.

Explanation of Solution

Introduction:

The resistance of a material from getting damaged under great pressure is called tensile strength.

The more the tensile strength of a material, more is its resistance from breaking or getting damaged under high pressure. If the engineer is choosing from among four products and he wants the product to be tear-resistant, he should consider the material with the greatest tensile strength for best performance.

Conclusion:

Since material 1 has greatest tensile strength among the four materials, it should be selected.
