Final answer:
A definitive answer on how much force is applied to lift the crate when a 220 N force is applied to the lever cannot be provided without further information about the distances involved and the efficiency of the lever.
Step-by-step explanation:
The question relates to the application of forces in physics, specifically how a lever amplifies an applied force to lift a weight, such as a crate. To determine how much force is applied to lift the crate when a 220 N force is applied to the lever, one would typically use the principle of moments, or the lever principle, where input force times input distance equals output force times output distance.
However, without additional information on the distances from the fulcrum (pivot point) to where the forces are applied, it's not possible to calculate the exact force applied to lift the crate. Assumptions about the efficiency of the lever or whether it's frictionless or not play a critical role too. Therefore, with the given information, we cannot definitively determine the force applied to the crate.
