A suitcase is a second-class lever because the load (suitcase contents) is between the fulcrum (hinge or handle) and the effort (force applied to lift or carry the suitcase). This lever arrangement allows for increased mechanical advantage, making it easier to lift and carry the load.

What makes a suitcase a class-2 lever?
A suitcase is a class-2 lever because the load (suitcase contents) is between the fulcrum (hinge or wheels) and the effort (lifting handle). This configuration increases the force applied to lift the load, making it easier to carry.
How does a second-class lever make work easier?
A second-class lever allows for a greater amount of force to be applied to move a resistance, as the effort arm is longer than the resistance arm. This mechanical advantage enables the lever to make work easier by requiring less force to lift or move a heavy load. Examples of second-class levers include wheelbarrows and nutcrackers.
Why is an oar a second class lever Giving reasons?
The answer is that it is NOT. It is a first class lever. "Class 1: the fulcrum is located between the applied force and the load. Example: the crowbar" - Wikipedia In regular use, the fulcrum of the oar is attached to the top side or edge of the water craft, which is between the force being applied by the rower and the "load", being the resistance of the water itself. This makes the oar a classic example of a first class lever.
How do 1 class lever make work easier?
A first-class lever makes work easier by increasing the force applied to move an object. The lever uses a pivot point, with the input force applied on one side and the output force generated on the other side. By changing the distance between the force and the pivot point, a first-class lever can amplify the force applied to the object.
How did a first class lever make work easier?
A first class lever makes work easier by allowing the force to be applied at one end of the lever to achieve a greater output force at the other end. This lever type increases the distance over which the force is applied, which reduces the amount of force needed to accomplish a task.
What makes a suitcase a class-2 lever?
A suitcase is a class-2 lever because the load (suitcase contents) is between the fulcrum (hinge or wheels) and the effort (lifting handle). This configuration increases the force applied to lift the load, making it easier to carry.
How does a carjack makes work easier?
This isn't that kind of carjack that you guys think it is, it a kind of tool for a car. It makes work easier because you can use it as a lever. You can use it as any kind of lever, a first class lever, a second class lever, ora third class lever. It works better as a third class lever. It works better as a third class lever because your using less work. Less work is being done with a third class lever because of he distance. The more the distance, the less force you need. Also, the more the distance, the less heavier it is.
What makes a class C fire?
The class C bottle rocket fires when you pull the lever.
What makes a class two lever class 2?
this is because their is load in btw the fulcrum and effort
How does a second-class lever make work easier?

This mechanical advantage enables the lever to make work easier by requiring less force to lift or move a heavy load. Examples of second-class levers include wheelbarrows and nutcrackers.
How is a hammer pulling out a nail a 3 class lever?
A hammer is a 3rd class lever. A third class lever has a load-effort-fulcrum configuration. What is interesting about a hammer is that though the load is the head of the hammer, the effort and the fulcrum are both in the hand. What makes it a 3rd class lever is that the effort is more in the hand and fingers, while the fulcrum is closer to the base of the hand at the wrist.
Why is an oar a second class lever Giving reasons?

This makes the oar a classic example of a first class lever.
Is racket badminton third class lever?
No. The racket is an extension to the arm, and the fulcrum is either the wrist or the elbow, with the force being the muscle and the load being the racket/badminton. This makes it a first class lever, unless you are swinging on an inside curl, not a normal swing, in which case it would be a third class lever. The difference is biceps (third class) versus triceps (first class).

What simple machine makes up a can opener?
Gears and wedges Sixth grader Actually their are 3 simple machines in a can opener. 1.A wedge 2.Wheel and Axle 3.A second class lever 8th grader
What are the 3 types of lever?
THREE CLASSES OF LEVER There are three classes of lever and each class has fulcrum, load and effort which together can move a heavy weight. CLASS 1 The workman uses a trolley to move the large packing case. The fulcrum is the wheel. CLASS 2The gardener uses a wheel barrow to lift tools and garden waste. The load is in the centre of the barrow CLASS 3 The fisherman catches the fish which becomes the load at the end of the lever.
