The biceps brachii acts as a class 3 lever to flex the arm. The deltoid also acts as a class 3 lever to abduct the arm, as does the teres major in adducting the arm. The triceps brachii, however, acts as a class 1 lever to extend the arm. In other words, when you're bending your arm or swinging it toward your body or away from your body, it's a class 3 lever. But if your arm is bent and you're straightening it, then your arm is a class 1 lever.
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.
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 believe that a screw driver is a third class lever ill update my answer later if wrong.

the pliers are first-class lever is because the pliers have the ankle and the parts to open or screw of something . the object is the front part and the the fulcrum is at the Angel, and the effort/force is in the middle
Yes, a screwdriver is a 2nd class lever. In a second-class lever, the load is located between the fulcrum (pivot point) and the effort force. When using a screwdriver, the fulcrum is the point where the screwdriver rests against the object being turned, the load is the resistance of the screw being turned, and the effort comes from the force applied to the handle.
