A hand cart is a 1st class lever because the fulcrum (pivot point) is between the effort (person pushing or pulling) and the load (goods being carried). This allows the person to exert force over a distance to move a heavier load with less effort.
No, a knife is not a 1st class lever. A 1st class lever is a system where the fulcrum is positioned between the effort and the load. In the case of a knife, it typically functions more like a 3rd class lever where the effort is between the fulcrum and the load, such as when cutting through food.
A needle can be classified as a class 1 lever. In a class 1 lever, the fulcrum is located between the effort (force applied) and the load (resistance). When a needle is used to sew, the pivot point acts as the fulcrum, the hand pressing down on the needle serves as the effort, and the fabric being pierced is the load.
The catapult is a 1st class lever
That is not an example of a 1st class lever. In a 1st class lever, the fulcrum is between the effort and the load, such as a seesaw. An example of lifting your chin off your chest, like during a sit-up, would be a 3rd class lever, where the effort is between the fulcrum and the load.
In a first-class lever, the fulcrum is positioned between the effort force and the resistance force. The fulcrum acts as a pivot point where the lever rotates around.
A wheelbarrow is an example of a second-class lever. The load is situated between the fulcrum and the force. The wheel-barrow is a 2nd class lever as the resistance is in between the force (effort) and the axis. A wheelbarrow is a class 2 lever. The fulcrum is the wheel or wheels in front of the wheelbarrow. You stand behind the wheelbarrow. The load is between you and the fulcrum.

1st class lever, with the axis of the elbow in the center of the force generated by the triceps proximally and the resistance of the hand and forearm distally
The answer to the question is: "No." A shock absorber is not a lever at all.
No, a knife is not a 1st class lever. A 1st class lever is a system where the fulcrum is positioned between the effort and the load. In the case of a knife, it typically functions more like a 3rd class lever where the effort is between the fulcrum and the load, such as when cutting through food.
it is a 1st-class lever
1st class,2nd class and 3rd class
1st class lever
A crane is a first class lever when it is winching in or out the rope attached to a load. The crane becomes 3rd class lever when it's boom is luffing, i.e. it is being lowererd or raised.
A garlic press is a class 2 lever
A needle can be classified as a class 1 lever. In a class 1 lever, the fulcrum is located between the effort (force applied) and the load (resistance). When a needle is used to sew, the pivot point acts as the fulcrum, the hand pressing down on the needle serves as the effort, and the fabric being pierced is the load.
