Schematic diagram of forceps force lever Why is forceps a hard lever? Why is the fulcrum the top? Please help draw the diagram of the forced lever and explain it in detail


This is the forceps force diagram, the force is power, power and resistance are rotating around a point, this point is the fulcrum. When we pinch things, the two forces are rotating around the top, so the top is the fulcrum. The vertical distance from the dynamic action line to the fulcrum is the arm, and the vertical distance from the resistance action line to the fulcrum is



Schematic diagram of lever on tweezers
Here's a picture. Thank you
Well, to add, I'm pepper





Lever principle of tweezers


The five elements of lever are fulcrum, dynamic resistance, dynamic arm and resistance arm
Tweezers are two pieces of metal and the end of the end together as a fulcrum lever
The power is the force exerted by your hand, and the resistance lies in the two very sharp heads of the tweezers. Therefore, the power arm of the tweezers is smaller than the resistance arm, which is a laborious lever. If you work hard, you can save distance, but not work



Draw the lever diagram when the claw hammer pulls out the nail


From left to right are: vertical downward gravity g; vertical symbol; resistance arm (dotted line, arm of force perpendicular to gravity); fulcrum O; (from bottom to top) power arm (dotted line, arm of force perpendicular to f action line); vertical symbol, force F. do not know how to catch up!
