Three masses, m A = 660 g, m B = 500 g, and m C = 730 g are connected by massles

Question

Three masses, mA = 660 g, mB = 500 g, and mC = 730 g are connected by massless, rigid rods. Masses A and C are on the x axis, with mass C at xC = 1.480 m. Mass B is located at xB = 0.544 m, yB = 1.380 m. Find the location of the centre of mass. Enter the x coordinate followed by the y coordinate.

Explanation / Answer

Centre of mass = m1x1 +m2x2... / (m1 +m2...)

Xcm = 660 x 0 + 500 x 0.544 + 730 x 1.480 /(660+500+730)

= 0.716 m


Ycm = 660 x 0 + 500 x 1.380 + 730x 0 / (660+500+730)


= 0.365 m
  
  
  
C.M. = (0.716m , 0.365 m)
