When it says to consider the shear force and bending moment diagrams from problem 6.1, does that mean we are taking those as a given for all of problem 6.2 and applying it to the questions?

For Part 1.a, are we supposed in include both locations where the magnitude of maximum normal stress occurs, since it doesn't specify tensile or compressive? Additionally, for Part 1.c, is the question asking for the magnitude of the maximum shear stress? The question doesn't specify, and if is supposed to be the magnitude, should we include the entire range of locations where it would occur?

Problem 6.1 is in meters, but problem 6.2 is in inches. Should they both have the same units or do we need to convert between the two?

Yes, that is correct! You should use the SF and BMD from P6.1 as a basis to solve P6.2

Part 1 - a: Yes, that is correct - max. compressive and tensile normal stress.

Part 1 - c: Yes, it is the magnitude. If there are multiple points experiencing this magnitude mention that in words.

I also have a question regarding the units. Are they suppose to be in inches or mm?

The units are in mm (not inches).

Thank you for the clarification this was confusing me a bit at first!

Are we just supposed to work with the centroid of the triangle because it says "at a point B just to the left", I do not see a point B?

I believe it means point B along the beam in problem 6.1. This is the point at the distributed triangular load of 2kN/m

In the problem statement for part 1, do they mean to ask for (x, y) coordinates or (y, z) coordinates? Seeing as the figures use (y, z) coordinates.

It is (x,y), not (y,z).

How do we find "I" for the triangle?

I = bh^3/36 for triangles. You can look it up, if needed.
