The examples of levers of second class are :-- . A bottle opener . Orange squeezer . etc. . wheelbarrow . door . nutcracker .
A broom is an example of a class three lever because the effort is in the middle of the fulcrum and load Some examples are . Broom . Hockey Stick . Arm . Boat Paddl…e . Baseball Bat In Level 3 levers the force is applied between the fulcrum and theload, as in tweezers. Example of third class levers are: . Arm, . Baseball bat, . Broom, . Doors, . Fishing rod, . Sling, . Tweezers, . Stapler, . Hammer nailing a nail, . An arm lifting weights, . Mouse trap, . Golf Club, . Catapult, . Diving board, . Nail clippers, the main body handle exerts the incomingforce, . Spoon, when used for flinging food, which uses the index fingeras the fulcrum, the thumb as the effort, and the load is thefood, . Mandible - *if you put the food item far back enough, it canalso be a 2nd class lever, . Fork in customary use, . Knife as utensil. Broom,tweezers In third class levers the force is between the resistance and theaxis. A baseball bat, golf club, shovel, and a broom are examplesof third class levers.
I think its a first class lever
ask ur mama abt it!
The position of the load, fulcrum, and effort are in differentspots. In a first class lever, the fulcrum is between the load andeffort. In a second class lever, the load is be…tween the force andfulcrum. And a in a third class lever, the force is in between thefulcrum and load.
teeter totter hammer nut cracker wrench
seesaw,light switch,crowbar and scissors
Neither. Scissors are a first class lever, because the fulcrum is between your effort and your resistance.
the difference is the position of the fulcrum. a first class lever has the fulcrum between the lode and applied force. a second class lever has the load between the fulcrum an…d applied force. A third class lever has the applied force between load and fulcrum. The load happens to be the thing that you are affecting in the system. On a seesaw the load and applied force changes as either kid goes up, but the lower kid is always the force and upper is the load with the fulcrum in the middle. this happens to be a first class lever. a second class lever could be a bottle cap opener with the fulcrum at the end the bottle cap(load) in the middle and you pushing (force) on the other. a third class lever are like tweezers with the fulcrum on the closed end, force is you pushing in the middle, and affected load is whatever you pick up. There are also compound levers like nailclippers, but by diagramming the whole system it should be pretty easy to discover that it is a first class lever. It's compund because of the use of a lever system
the fulcrum between the effort and load. B.. effort applied in the same place. C.. two loads and fulcrums. D.. the fulcrum at one end of the lever.
The forces in both move in the same direction as the load. Also,the fulcrum is on the end of the lever in both. Hopefully this helped......... :-) :-) :-) :-) :-) :-) :-) :-) …:-):-)
third class all the way
1) In second-class levers, the effort arm is always longer than theload arm. In third-class levers, the efform arm is always shorter thanthe load arm. 2) In second class lever…s, the distance traveled is always greaterthan the load distance traveled. In third-class levers thedistanced traveled is always shorter than the load distancetraveled. 3) In second-class levers, the effort force is always less than theload force. In third-class levers, the effort force is alwaysgreater than the load force. A Second Class lever has the load in the middle, between the effortand the fulcrum, so its Mechanical Advantage is always greater than ' 1'. A Third Class lever has the effort in the middle, between the loadand the fulcrum, so its Mechanical Advantage is always less than ' 1 '.
That's a tall order. I may need a lever to get up that high. Forall the tools I will mention, some of them from a lever when youhold onto them and use them, others are levers …in themselves. Let'shave some fun, so here we go. First Class levers are like a teeter-totter or see-saw, a pair ofscissors - which is two 1st class levers together, but I'll countas just one. There is also one in your elbow, one in your ankle,and another one in your jaw. That makes five. Second Class levers can be found in wheelbarrows, nutcrackers, yourjaw and ankle, and vise grips; that's five again. Let's make it sixwith a canoe paddle, it's also a second class lever when you paddlewith it in water. The last one is the easiest: Third Class levers can be found in lots more places, they are muchmore common. Here's a short, but diverse list: broom, fishing pole,hammer, your knee, pen, pencil, the joints in your fingers and toesnot counting the first knuckle, a tennis racket, oh shucks justabout every sporting device that you swing is a 3rd class leverwhen in use. The gas peddle in your car. Chopsticks, wooden spoons,fork, knife, spoon, toothbrush. And there are a whole lot more of all three.
