  • I have a beam that's 331 centimeters in length too, but it's not aluminum.

  • wow thats cool

  • @fotsifotsi as he said he puts more energy into it

  • how did he manage to increase the volume of the sound just by rubbing the metal?

  • hahaha didnt it sound like a forklift backing up

  • Is there a way to find out how much energy is in the rod from the volume of the sound?

  • How do you calculate wave length for a given rod?

  • BAHHHH!!! He dropped his ruler!!!!!
