Challenge Problems
Push your limits with advanced challenges
A block and tackle system has a load of 600 N and lifts it with 100 N of effort over a distance of 4 meters for effort and 2 meters for the load. Calculate M.A., V.R., and Efficiency.
💡 Hint: Use the respective formulas step-by-step.
You have a lever giving an M.A. of 3. The load moves 2 meters when you move the effort for 6 meters. Is the efficiency greater than 50%?
💡 Hint: Check the relationship between M.A. and V.R. for efficiency.
