Traverse Survey

Traverse surveying is a popular method of surveying. Traversing is that type of survey where several connected survey lines form a framework and the directions and lengths of the survey lines are measured with the help of a tool to measure angles and tape or chain respectively. Traverse networks involve placing survey stations in a queue or trail and using pre-tested points as a basis for looking at the next point. This type of surveying is different from Tacheometric surveying, where only angles are measured and the process of chaining is reduced.

Question

100%

As an engineer working for the oil-based multinational company Petronas, you are re-
checking the calculations done by the consultants as shown in Figure 3. However,
upon submission, your chief engineer told you to sit down and asks you to re-calculate
the following back to check if you really understood the calculations;
(a) Find the distance ỹ to the centroid of the beam's cross-sectional areas and
calculate the moment of inertia about the x'axis.
(b) What is the moment of inertia of the beam's cross sectional area about the y-
axis?
(c) Your chief engineer further asks "It is often the case that the moment of an
inertia for an area is known about an axis passing through its centroid. What
can then be said about the moment of inertia of the same area about a
corresponding parallel axis?"
