Where are the missing 15 cm ?
What happens when you pull the arm out again and 15 cm are missing? Will the lower arm fall off...??
Now imagine that you move your arm up with speed n... ..and the part inside only follows with n/2
Of course this is just a simplified example... ...please note that I am too lazy to calculate how much of the arm is really missing.
