For the section below, you need to work out the centroid position (d, and d̟ from the origin indicated) and then the values of ly, Iz and lyz. Choose the range for each of your values; if your value is outside all of the ranges, you have made an error somewhere.

Hand written work only, pls make little comments so I know why you took that step

Calculate the position of the centroid. Use the axes of the figure. It is possible to make the calculation from three geometric shapes only. Answer: Xc = 35.1 cm Yc= 18.3 cm

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

1.1.2 - Show all work please.

Note: EI is a constant for the beam Images attached.

let R=73mm. -The x-coordinate of the centroid is _____ mm. - The y-coordinate of the centroid is _____ mm.
