Explain the steps that could have been taken to prevent disruption of the earth in the following scenario,
The 2016 Olympics are going to be held in Rio de Janeiro, Brazil. A team of engineers is under extreme time
constraints to build an enormous arena to host the events. As the team breaks ground, a small sinkhole-like area collapse occurs beneath them.
It is to be noted that in order to prevent the kind of disruption described above involving a sinkhole the following steps or procedures can be taken by the civil engineering team responsible.
What are the steps required?1) It is to be noted that the first step in determining the capacity of a soil type to hold the weight that will be placed on it is to do a geological survey. The purpose of this is to identify if there are any potential geographic hazards that mujst be taken in to account or avoided completed during the construction process.
2) Where it is possible to build regardless of the hazard, there must deployment of soil stabilization technique to prevent any collapse of the structure above such grounds or area.
3) During construction, close monitoring must be carried out especially during excavation.
The above will help ensure that the disruption of the earth is prevented

1. What is the major difference between a machine screw and a bolt?
Answer:
The major difference between a machine screw and a bolt is the way they are used. A machine screw is designed to be threaded into a tapped hole or nut, while a bolt is designed to pass through a hole in a part and then be secured with a nut on the other side.
Machine screws have a uniform diameter along their entire length and are typically threaded all the way to their head. They are commonly used in metalworking applications where a tight fit is required. Bolts, on the other hand, come in a variety of lengths and diameters and are usually partially threaded, with an unthreaded shank section that passes through the hole in the parts being joined.
Another difference between machine screws and bolts is that machine screws are generally smaller and used for lighter-duty applications, while bolts are larger and used for heavier-duty applications. Bolts are often used in construction, automotive, and other heavy-duty applications where high strength and durability are required.
