Item no.: P2132701 Principle If an oscillating system is allowed to swing freely it is observed that the decrease of successive maximum amplitudes is highly dependent on the damping. If the oscillating system is stimulated to swing by an external periodic torque, we observe that in the steady state the amplitude is a function of
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.: 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
