Final answer:
A lever is a simple machine that can amplify force or change the direction of force. The lever in this question has a handle at its end with an exerted force of 2000 N at the handle tip, acting on the x-y plane at a 27° angle.
Step-by-step explanation:
A lever is a simple machine that consists of a beam attached to a fixed point called the fulcrum. It can be used to amplify force or change the direction of force. In this question, the lever has a handle at its end with an exerted force of 2000 N at the handle tip, which is acting on the x-y plane and has a 27° angle. The lever's efficiency can be calculated by comparing the input force to the output force. However, more information is needed to determine the efficiency of the lever in this specific case.
