Item no.: F14 Introduction it is generally designed as a venturi meter to measure the flow rate or flow velocity, includes liquid or gas, inside the piping system of varying cross-section. Base on the conservation of flow as well as mechanical energy (Bernoulli equation), i.e. V(flow velocity) x A( cross-section area) =constant and P (hydraulic
Item no.: F03 Introduction Why does spring water come out the ground continuously? How does a ship bear large loads while sail on the sea? How did Archimedes test and figure out the material of pure gold? How does a magician put a needle through a ballon without explosion? That is due to some special
Item no.: F13 Introduction The Young Modulus, named after Thomas Young (1773 to 1829) who was an outstanding British polymath in material fields, is usually used to define the proportionality of normal stress and normal strain for metal material subjected to external force. Such proportionality constant only prevails within the working region below elastic limit i.e.,
Item no.: F12 Introduction Base on Newton’s second law and energy conservation, we will forward torque and rotational theory to study harmonic motions in reversal compound pendulum and torsion pendulum, which have been widely used in practical application such as torsion or pendulum clocks, crank system of engine, mechanical pressure gage, damping device and rotary
Item no.: F11 Introduction As our daily appliance, the rotational device could be found everywhere at anytime. Just like the rolling wheels in car’s motion, gyroscope in the steamer, even the spinning skill in the athletic game, hurricane arisen from air of large vortex and the existence of spiral galaxy in universal space, they all
Item no.: F07 Introduction These experiment kits is designed to demonstrate the dynamic projected motion, which provides the user an useful manner to understand the conservation of mechanical energy. Here the transformation of potential/ kinetic energy in elastic/inelastic collision will be clearly discussed. When the steel ball is jetted horizontally with three different velocities in
Item no.: F08 Introduction By means of air resistance (also called drag), parachute helps the pilot drift to the ground slowly and safely. That is attributed to the drag counteracting free falling initiated by gravity acceleration. To meet this purpose, a comprehensive experiment kit features several characteristic are proposed: (1) experimental gravity acceleration might be
Item no.: F02 Objectives With the aid of optical timers, slider’s acceleration to verify Newton’s Second Law of Motion could be determined. Slider’s acceleration along the component of inclined plane, ‘gsinθ ‘ is found to be dependent on the inclined angle, but irrelevant to slider’s mass. Conservation of momentum in elastic and inelastic collisions. 4.Kinetic

Torque balance- parallel force of plummet, lever experiment on the different/same side, multiple torque, wheel & axle, the center of mass& gravity. Force of inclination-maximum static friction, coefficient of static friction, coefficient of dynamical friction and pulley system. Pulley- single/double sheave pulley, the comprehensive experiment of pulley. A
