Answer:
Normal force = 0.326N
Explanation:
Given that:
mass released from rest at C = 3.7 g = 3.7 × 10⁻³ kg
height of the mass = 1.1 m
radius = 0.2 m
acceleration due to gravity = 9.8 m/s²
We are to determine the normal force pressing on the track at A.
To to that;
Let consider the conservation of energy relation; which says:
mgh = mgr + 1/2 mv²
gh = gr + 1/2 v²
gh - gr = 1/2v²
g(h-r) = 1/2v²
v² = 2g(h-r)
However; the normal force will result to a centripetal force; as such, using the relation
N =mv²/r
replacing the value for v² = 2g(h-r) in the above relation; we have:
Normal force = 2mg(h-r)/r
Normal force = 2 × 3.7 × 10⁻³ × 9.8 ( 1.1 - 0.2 )/ 0.2
Normal force = 0.065268/0.2
Normal force = 0.32634 N
Normal force = 0.326N

Answer:
Environmental assessments (EAs) are an important component of any civil engineering project. Delgado Engineering has been contracted to design and assess a multibillion-dollar urban rail center in a city, which is divided in the middle by a river. The center will be built on a previously unused island in the center of the river. For each of the four types of civil engineers (construction engineer, geotechnical engineer, structural engineer, transportation engineer), explain why they should be involved in the project—or why they would not be relevant to the project—and what their role would be. Then describe how the EA would proceed, including what might be included in the environmental impact assessment process, such as the use of geographic information systems. Finally, explain what might be in the environmental impact statement or why you think there may be a finding of no significant impact.
