Product Description

Description:

This product is part of a range that explores freevibrations in simple one degree of freedom systems.

It introducesstudents to key scientific terms such as:

  • Simple harmonic motion  
  • Frequency of oscillation
  • Shear modulus
  • Polar moment of area
  • Mass moment of inertia
  • Phase difference between displacement and its derivatives

This product fits to the sturdy Test Frame for study ordemonstration. This product includes a rotating disc or rotor at the end of aslender rod. You can compare this with the mass-spring system, except itreplaces mass with the rotors mass moment of inertia and the spring with thetwisting of the rod. A back panel fixes to the Test Frame. The panel holds twovertical runners. The runners hold a chuck that securely grips a specimen rodat any position along its length. The bottom of the rod fixes to a rotor thatis free to rotate. A bushing ensures the rotation remains along the axis of therod, and supports the rotor during setup.
