Question 1: Determine y, which locates the centroidal axis x for the cross-sectional area of the T-beam. As mm 75 mm. 20 mm 150 mm 20 mm

Consider the cross section shown in (Figure 1). Suppose that b = 112 mm Part A Determine the major principal moment of inertia Imar of the cross section about the principal axis having an origin at point C. Express your answer to three significant figures and include the appropriate units. ? Imax = Value Units Submit Request Answer Part B Determine the angle 0,, as measured on the cross-section from the positive z axis. Figure Express your answer using three significant figures. Enter positive value if the angle is counterclockwise and negative value if the angle is clockwise. Vol AEO vec ? 10 mm - Op, = 80 mm Submit Request Answer 80 mm. 10 mm Part C 10 mm - Determine the minor principal moment of inertia Imin of the cross section about the principal axis having an origin at point C.

Find: Using the Principle of Virtual Work, calculate the vertical deflection of Point E, and the horizontal deflection of Point F for the truss shown. Assume E = 10,000 ksi and the following cross-sectional areas: Parts AB, BD, DF, and FH have A=4.0 in? while all other parts have A=1,5 in?. Summarize the results of your calculations in a table so that it is easy to review (similar to calculations shown in class example). 5 kip B F 14 ft E G H 30 kip 10 ft 10 ft 10 ft 10 ft

The maximum deflection for the cantilever-beam below is no more than 0.03m.Macaulay’s method of double integration should be used to determine the second moment of area of the beam cross-section (I) (Please let's the final unit be in mm^4 and also provide a final check)E = 200 GN/m2  can someone please answer this question in detail who is confident in this topic with step-by-step calculations pls.  I've asked this question twice now and I've gotten different answers each time so I'm at a bit of a loss. (Pls don't respond to this if you have already responded previously) Thank you
