How do you measure concrete?
Cubic feet, Cubic yards, Cubic Meter
Which is stronger solid steel rod or hollow steel pipe?
On a per pound basis, steel pipe is stronger in bending and is less likely to buckle in axial compression.

What is the meaning of soil reinforcement?
Soil reinforcement is the act of improving soil strength to enable it support or carry more load.
Two common examples are:
a) Mixing a soil amendment such as lime into weak clayey soil and re-compacting to improve soil-bearing capacity (often done under the road base in highway construction)
b) Installing plastic or composite webbing layers (called geo-grid material) alternating with compacted soil to produce a stronger sloped soil structure (often done on steep roadway embankments to improve strength and stability)
What is aggregate?
Aggregate is the component of a composite material used to resist compressive stress.
What year was the keystone power plant in Indiana County constructed?
1967 began commercial operation on unit 1.
What is the force exerted by the Tacoma narrows bridge?
The force exerted to the Tacoma narrows bridge was initially the wind resistance. The wind resistance caused the whole bridge to act as a system with forced vibration with damping.
