Experimental Apparatus for Mechanics Laboratories
Our experimental apparatus for mechanics laboratories are specially designed to promote physics experimental teaching and learning. Topics cover force, motion, oscillation, and wave mechanics in general physics. They are priced to meet the budgets of educational institutions. All instruments/ systems come with self-paced and comprehensive experimental instructions/manuals. |

LEMI-10 Measurement of Young's Modulus-Stretching Method |
|
This apparatus is designed to demonstrate that the deformation of a metal wire under load is proportional to the strain applied. The load is applied parallel to the axis of the wire at one end while the opposite end of the wire is fixed. |
| |

|
LEMI-12 Measurement of Young's Modulus-Hall Sensor Method |
|
This apparatus is designed to study the deformation characteristics of thin metal sheet samples under load. Deformation is created by applying a small force on the sheet. A micro-displacement sensor based on Hall effect is used for measuring the deformation. |
| |
|
|
LEMI-13 Measurement of Young's Modulus-Resonance Method |
|
This apparatus is designed to study the deformation characteristics of a metal round bar by using the dynamic vibrational resonance method. The Young's modulus can be determined by measuring the vibrational resonance frequency of the sample. |

LEMI-16 Simple Pendulum with Electric Timer |
|
Using an integrated Hall sensor and electronic timer,this apparatus can accurately measure period under large swing angle in a few swing cycles, so the air damping of the pendulum angle can be ignored. It is possible to acquire the precise value of the gravitational acceleration. |

LEMI-18 Rotational Moment of Inertia Apparatus |
|
This apparatus uses the three-string pendulum method for the determination of rigid body moment of inertia. A photoelectric sensor combined with a time counting device are used to measure the torsional oscillation period of the hanging plate. |

|
|
LEMI-21 Simple Harmonic Motion and Spring Constant |
|
This experimental apparatus improves traditional versions on the reading device by using a pointer plus a reflective mirror combined with a vernier and on the timing device by using an integrated Hall sensor. |

LEMI-25 Pendulum & Projectile Apparatus |
|
This pendulum and projectile experimental apparatus studies the collision of two objects, as well as the simple pendulum motion before collision and the projectile motion after collision. It has features: reliable structure, parallax eliminated, friction influence reduced, and high experimental accuracy. |

|
LEMI-60 Double-Grating Comprehensive Experiment Apparatus |
|
This apparatus is designed to study damped vibration and forced vibration, analyze displacement resonance and velocity resonance, observe variation vibration amplitude, measure the length of Talbot self-imaging, and observe Doppler effect. |
| |
|
|
LEMI-61 Double-Grating Weak Vibration Measurement Apparatus |
