Determine y (y bar) and x (x bar) for the cross-section shown below. | 1-41- 1.5"-1 Question 1 Points out of 1.00 P Flag question Not yet answered y (y bar) = Select one a. 2.02 in b. 1.72 in C. 3.48 in d. 2.48 in e. 1.52 in

Answer 1

Given, (orign) o Flin sklin sk 13 in > X To get X and y, Let us consuder this Composite plane into two parts A-square with Arua, A = 3.5x3.5 int B - Reclangle caith Area, Az = {x1.5 in2 Question . T _ A, Y + A2 Y₂ 7 ne, A = 3.5X305= 12.25in A2 = 1X105 = 1.5in2 y = distance forom centre of grauity of square 'A' from origin o along y direction Scanned with 3.5 - 1.75 inch CamScanner a

y = distance from . C. G of Rectangle. 'B' to the origin in y directions Y = 3.5+ (1.5 = 4.25 in Then, ✓ = (12.25 X 1,75) +(1.584,25) 12.25 +1.5 y = 2.05 in Hence, option. (a) is correct Question ③ (2) similarly, X = (A x + A₂012) 20,= 3,5 = 1.75 in X = It t = 1.5in Then, x = (12,25% 1075) + (1.5*1.5) 12.257 165 * = 1.72 hence, option @ is correct ALTA2 x = 1672 y = 2.06 Scanned with CamScanner
