because pressure gauges are attached to most tire pumps, there's often very little need to calculate psi in this context. People working with hydraulics also use psi, often to determine the amount of force that potable water or waste water ...
1. Repair or replace? Determine if the concrete is structurally sound.If a sidewalk has either heaved or dropped at almost every joint, repairing it will not provide a long-term solution. The slabs are likely still moving. If the slab has so much sand and gravel on the surface that ...
Learn how to drill in concrete. The best guide to knowing what type of drill is required for concrete slabs. Diamond concrete drilling cost. The best drilling for cement etc.
Alas, it is impossible to determine whether subjects are affected by once-motivated reasoning or "fully Bayesian" by observing how they respond to new information. Any once-motivated reasoner has a Fully Bayesian Equivalent (FBE) who only cares about accuracy and has a different objective prior ...
universities or by searching for geotechnical engineering services in the phone book. The lab can test the sample's compressive strength. The sample should be able to withstand pressure of 300 pounds per square inch (PSI); this is the standard in earthen material building codes [source: Branch...

Most concrete patios, and other concrete slabs, are 4 inches thick. Building codes across the country usually require a thickness of 3.5 inches and compressive strength of 3,000 PSI. However, many things determine whether a concrete patio should be thicker, or incorporate rebar/reinforcement mesh...
In engineering mechanics classes, the study of thermal stress and its effect on various materials is important. Cold and heat can affect such materials as concrete and steel. If a material is unable to contract or expand when there are temperature differ
We sought to determine the impact of performing a concurrent cognitive or motor task during stair-climbing. We hypothesized that a concurrent cognitive task will have a greater impact on stair climbing performance compared to a concurrent motor task and that this impact will be greater on a high...
While this line of reasoning is likely correct in most circumstances, we will show here that—as a matter of principle—there is no bound on Tc/ρs(0). We outline a concrete model where ρs(0) can be made arbitrarily smaller than ρs(Tc) (Fig. 2). ...
