Question

Problem 12.6 The three masses shown in the figure(Figure 1) are connected by massless, rigid rods. Assume that m 250g and -260g m2 Figure 1 v of 1 10 cm 10 cm A O 100 g What is the z-coordinate of the center of mass?

Explanation / Answer


m1 = 250 g       x1 = 0     y1 = 10 cm


m2 = 260 g       x2 = 10     y2 = 0 cm

m2 = 100g         x3 = 0      y3 = 0

x coordinate of CM = xcm = (m1*x1)+(m2*x2)+(m3*x3)/(m1+m2+3)


Xcm = ((250*0)+(260*10)+(100*0))/(250+260+100) = 4.26 cm

--------------------------

part(B)

y coordinate of CM = Ycm = (m1*y1)+(m2*y2)+(m3*y3)/(m1+m2+3)


Ycm = ((250*10)+(260*0)+(100*0))/(250+260+100) = 4.09 cm
