The scissor lift
Engineers (Advanced), mission M1 Force, Mass & Motion, lesson 4 of 6.
Hook
Scissor lifts raise workers 10 metres. How does a small rack push that high?
Fair test
Measure platform height vs crank turns. Is the relationship a straight line?
Bonus challenge
Where is the lift wobbliest? Add one brace and test again.
The build
- 🛗 Scissor Lift: Turn the crank and the platform climbs straight up on criss-cross legs. (level 3 of 5, about 45 minutes, 29 steps)
