At what distance from the fulcrum should a force of 10N be applied to balance the force of 45N acting on the lever arm 0.15m long?
| February 23, 2021 | education
Data: F1 (the force to be applied at the desired distance from the fulcrum) = 10 N; F2 (the force to be balanced) = 45 N; l2 (length of a given lever arm) = 0.15 m.
The distance from the fulcrum can be determined from the equality: F1 * l1 = F2 * l2, whence l1 = F2 * l2 / F1.
Calculation: l1 = 45 * 0.15 / 10 = 0.675 m.
Answer: A force of 10 N must be applied at a distance of 0.675 m from the fulcrum.
