An amusement park ride consists of airplane-shaped cars attached to steel rods. Each rod has a length of 14.0 m and a cross-sectional area of 0.000780m^2. When operating, the ride has a maximum angular speed of 8.00 rev/min. How much is the rod stretched?
Take the Young's modulus for the rod to be Y = 2×10^11 Pa and the free fall acceleration to be g = 9.80 m/s^2
Umm... I am really just stumped on this one. Really its just the rotation part that's messing me up. What outward force would be caused by the rotation? Would the rotation even change the amount stretched from a still position? Haha, I would really appreciate a push in the right direction.
