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.

i think yes
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.
Is it a third class
well you take buisness then you screw the teacher
class 6 is impossible, so class five is the most difficult you can survive and do it again. if you screw up death is the common outcome. A safety team is a must!
