The Tachometer 3D puzzle from UGEARS' STEM Lab collection is a fully operational DIY wooden model of a tachometer, ready for you to assemble. When the handle is rotated, movement is transmitted through a reducer, increasing the RPM and displacing twin weights in the centrifugal unit. The higher the RPM, the more centrifugal force separates the weights, shifting a movable axle with flywheel. A pointer mechanism (dial) is fixed to the axle; the more the axle shifts (higher RPM), the more the dial arrow deflects, indicating higher speed rotation.
Ugears STEM puzzles are designed to suit different age groups with a special focus on learning component. The assembly of the model will be interesting and won’t take much time.
Model size: 9.4*4.1*4.8 in (24*10.3*12.3 cm)
Package size: 8.1*7.4*2.5 in (20.5*18.8*6.3 cm)
