If you are looking for stem activities for your 8 year old or stem a 9 year old look no further.
The UGEARS Gearbox is a comprehensive educational model, an interactive study guide of the mechanism designated for learning its essentials and principles of operating.
After you put it together, you can experiment with the Ugears manual Gearsbox, choose I, II, III, or reverse with a kinematic pair of gears with different ratios and, rotating the actuator handle clock-wise, you can watch and control the rotation speed of the layshaft and drive shaft.
In a Position “N” – idle in which both clutch gears of layshaft remain uncoupled and idling; the First Gear makes the layshaft and gears rotate with the lowest speed; the Second Gear lets the drive shaft along with the flywheel rotate with an average speed and the Third Gear allows the layshaft and all gears rotate with the highest speed.
Switch on the Reverse gear and watch how the driving clutch gear shifts to the left towards gear “R” and connects to it transferring the rotation to the lower gear arrangement and propelling the layshaft and all gears to rotate in reverse.
