A compact 60-kg object is attached to one end of horizontal 40-kg uniform steel tube 2.4m long. What is the distance from the loaded end to the center of gravity of the object-tube system?
Measuring from the end with the 60 kg load, and calling the distance to the Center of Mass x,
40*1.2 = (60+40)x
x = 48/100 = 0.48 m
