Homework Statement
The machinist's square shown in the figure consists of a thin, rectangular blade connected to a rectangular handle. Determine the x and y coordinates of the center of gravity. Let the lower corner be x=0, y=0.
Homework Equations
x_cg = (m_1 * x_1)+(m_2 * x_2).../(m_1+m_2+...)
y_cg = ...... (same thing, but y)
The Attempt at a Solution
pI have gotten an answer, but it is not matching up with the back of the book. Here are the numbers I used to get my answer:
x_1 = 4cm
x_2 = 12cm
y_1 = 11cm
y_2 = 3.0cm
for x_cg I have: [(4cm*40g)+(12cm*80g)] / (40g+80g)= 9.3cm
for y_cg I have: [(11cm*40g)+(3.0cm*80g)] / (40g+80g)= 5.67cm
What did I do wrong? Thank you for any help!
