The fulcrum is between the load and effort distinguishes first class levers from both second and third class levers.
Explanation:
Lever is a bar that can rotate around a fulcrum. The levers can be divided into three classes: First Class Levers (Interlocking Levers), Second Class Levers (Inter-Resistant Levers) and Third Class Levers (Interpotent Levers). In the first-class levers, the fulcrum is between the point of application of the force of action and that of the resistance force.
The fulcrum is between load and effort distinguishes first class levers from second and third class levers.
The Weak AI thesis is the claim that artificial intelligence research may help us explore various theoretical models of human mental processes while acknowledging only simulate mental activities because weak artificial intelligence may implement Limited part of the mind but would not actually be mind .
