1- Determine the location y of the centroid C of the beam having the cross-sectional area shown - 150 mm 150 mm 20 mm 20 mm 150 mm 150 mm 10 mm 15 mm y 13 10 mm The missing data is 83 mm NB: each student inputs the missing data (in red dashed-line). The missing data is the last two digits of your ID number. If your two last-digits number is smaller multiply by 10 (example if you get 19→19x10 = 190)
