|
LEMI-1 Young's Modulus Experiment Unit |
|
We designed this apparatus to demonstrate that the deformation is proportional to the strain for a metal wire under load which is parallel to the axis of the wire and is applied to one end while the opposite end is held fixed. |
| |
|
|
LETI-1 Thermal Expansion Experiment Unit |
|
This unit utilizes a Michelson interferometer to determine the linear expansion coefficient of the sample materials very accurately. |
