Where is the center of mass of a semicircular wire of radius R that is centered on the origin, begins and ends on the x axis, and lies in the x,y plane?

Four very thin rods, each 6.3 m long, are joined to form a square, as part (a) of the drawing shows. The center of mass of the square is located at the coordinate origin. The rod on the right is then removed, as shown in part (b) of the drawing. What are the x- and y- coordinates of the center of mass of the remaining three-rod system? ty +x +x (a) -0.75 x coordinate of the center of mass = Number Units m y coordinate of the center of mass = Number Units m

Find the center of mass (x̄, ȳ, z̄) of the block, given:   L1 = 5 in,   L2 = 4 in,   L3 = 6 in,   L4 = 5 in,   L5 = 3 in,   L6 = 8 in
