AG Mechanics CDE Practice Exam

Concrete has low ________ strength.

1. compression

2. shear

3. torsion

4. tensile

The correct answer is: compression

Concrete has low compression strength. This is because concrete is a material that is strong in compression but weak in tension. When a load is applied to concrete, it is much better suited to resisting forces that compress it rather than forces that pull or stretch it apart. This is why the correct answer is that concrete has low compression strength. Shear strength, torsion strength, and tensile strength are not the primary weaknesses of concrete. While it is important to consider the overall strength of concrete in various aspects, its low compression strength is a well-known characteristic.
