A screw driver is a class 3 lever, where the effort is between the fulcrum (the place where the screwdriver pivots) and the load (the resistance of the screw being turned).
Yes, a screw can be considered a first-class lever. The effort (force applied to turn the screw) acts on the handle, the fulcrum is at the screw's axis, and the load (resistance being overcome) is the material being drilled through.
A screw driver is a lever. The bigger diameter of the handle compared to the tip amplifies the turning force.
First Class
A screw is a modified form of a wheel and axle, which is considered a type of lever. In a screw, the shaft acts as the axle and the threads act as the wheel, allowing rotational motion to convert to linear motion.
screw and wheel and axle A screw or a twisted inclined plane seems to be the answer you seek.
i think yes
I believe that a screw driver is a third class lever ill update my answer later if wrong.
Is it a third class
First Class
A lever works on the principle of using torque. A screw driver is used as a lever because the relatively broader handle produces much more torque for the same force as compared to the narrower blade of the screw driver.
