What else can I help you with?
Place 4n worth of force 0.2m from the fulcrum where would you have to place 2n in order for the lever to balance?
The force is equal to the mass times your lever arm. If 4n is placed 0.2m from the fulcrum, you have 0.8 force units on you lever arm. This would imply that a mass of 2n should be placed 0.4m from the fulcrum in the opposite direction. This would give you 0.8 force units on both sides, thereby balancing the lever.
Where on your arm would you find the fulcrum?
The elbow in the hand is analogous to the fulcrum in a lever
What is the pivot point on lever called?
The pivot point on a lever is called the fulcrum. It is the point around which the lever rotates when a force is applied to one end of the lever.
What would be the ideal mechanical advantage of the lever if the fulcrum 2m to the right?
The ideal mechanical advantage of a lever is calculated by dividing the distance from the input force to the fulcrum by the distance from the output force to the fulcrum. In this case, with the fulcrum 2m to the right, the mechanical advantage would be different for different positions along the lever.
What are examples of lever and fulcrum?
An example of a lever is a crow bar. The fulcrum would be where the bar touches the ground, that is what the bar is rotating around.
Would it be easier to use a lever and fulcrum?
Depends on the job at hand. The most common use is to multiply force so you can move something that weighs more than you can lift on your own. In doing this you give up distance. Place the lever and fulcrum so that the fulcrum is close to the 'load'. When you push on the long end of the lever it moves a long distance with a small effort, The load will be lifted a shorter distance.
On which type of simple machine would you find a fulcrum Explain what a fulcrum is?
A fulcrum is found on a lever, which is a type of simple machine. A fulcrum is the fixed point around which the lever pivots or rotates. It helps to transfer and multiply force applied to one end of the lever to lift or move objects at the other end.
How would changing the placement of the fulcrum effect how you use a lever?
yes it would
What class lever would an engine hoist be?
An engine hoist would be a class 2 lever. The load (the engine being lifted) is between the effort (the force applied) and the fulcrum (the pivot point). This type of lever is useful for providing a mechanical advantage when lifting heavy objects.
What the solid bar that rests on a fulcrum?
The lever? There are probably other names for it, but i was always taught the fulcrum, lever, and load. Load closer to fulcrum, easier to lift load. (longer lever= mechanical advantage) This would fall under simple machines in science class.
How is a baseball bat like a lever?
It seems the baseball would be the load, the bat and your arm would together form a lever, and your shoulder would be the fulcrum.
What type of a lever is a hand pump?
It would be a lever class one lever as the fulcrum is in the middle
