representation of a purely harmonic reciprocating motion

Description:

• The crank slider, unlike a normal crank mechanism, generates a purely harmonic stroke movement.
• The KI 120unit can be used to generate and study purely harmonic stroke movements.
• The experimental unit comprises a rotating crank disk, connecting rod and fixed cylinder.
• The connecting rod is connected to the crank disk on one side via a crank.
• Changing the position of the crank on the crank disk adjusts the crank radius in three positions.
• At the other end, the connecting rod is connected to the fixed cylinder.
• This end models the piston.
• The angle is adjusted using the crank disk, and an angle scale is integrated into the base plate.
• A millimetre-precise steel ruler is attached to the cylinder to measure the stroke.
• The elements are mounted on a base plate.
• Two handles make it easy to carry and stack the unit.
