What are the four parts of the lever?
load arm, effort arm, load, effort, fulcrum!
How much force would a biceps muscle inserted 4 cm from the fulcrum need to hold the arm stationary at a 90 percent angle?
Only a very small force if the arm only has to be supported. What other weights do the arm carry and at what angle does the biceps attach to the fore-arm? What is the distance to the hand from the fulcrum and what is the arm weight (assuming a weight is in the hand and arm weight has to be added to the weight-in-hand)? The length of the hand to fulcrum is also required. There is no such thing as 90% angle: 90 degrees perhaps?
How can you calculate the maximum distance of a mousetrap car without knowing force or acceleration?
First off, A mouse trap lever only moves 180 degrees. So you would take the length of your mouse trap pulling arm (e.g. 12''), and multiply it by two (24'') Now you have the diameter of the circle if the mousetrap arm could spin a full 360 degrees. So to find the circumference of that invisible circle you would multiply the diameter by pi (24'' x 3.14 = 75.36'') Now since the mouse trap arm only moves 180 degrees, you would divide your answer by 2, because 180 is half of 360. (75.36'' divided by 2 = 37.68'') Now that you have the distance that the arm travels you need to find the circumference of the axle your pulling wheels are on. Say that your axel has a quarter inch diameter ( .25'' ) you would do the same thing as before: (e.g. .25'' x pi [3.14] = 0.785'') Now you would divide the distance your lever arm moves by the circumference of your axle (e.g. 37.68'' divided by 0.785'' = 48) this means that the string tied to the tip of the arm would wrap around the axle 48 times. Now for the final step the circumference of the wheels, just do the same as before, diameter multiplexed by pi. (e.g 5'' x 3.14 = 15.7'' ) Now that you know how many times the axle will rotate (48 times) and how far it travels each rotation (15.7'') all you have to do is multiply them! e.g. (48 x 15.7 = 753.6'' ) or 20.93 yards, one fifth of a football field! But keep in mind this is in a world with out friction. I apologize if I was at all confusing, im not too good at teaching things, haha. I hope I helped!
How big is 36 inches?
36 inches = 3 feet = 1 yard ~= distance between the nose and fingertips of the outstretched arm of a man.
How do you use the equal arm balance?
Before you begin using an equal arm balance, you must make sure the riders are an equal distance apart, and make sure the balance is balanced. Then, place the object(s) on one side of the balance, and the object(s) that you want to compare them to. Whichever object is closer to the ground is heavier. If the objects are equally levelled, they have equal mass.
Is the arm lever a distance multiplier or a force multiplier?
Well, i'd say its both. depends on the case to specify when it is a force multiplier or a distance multiplier.
Can a force produce a torque when there is no lever arm?
No, a torque is produced when a force is applied at a distance from an axis of rotation. If there is no lever arm (distance from the axis of rotation), the force will not create a torque.
The product of force and lever-arm distance in producing rotation is?
The product of force and lever arm distance in producing rotation is torque. Torque is a measure of the rotational force applied to an object and is calculated by multiplying the force applied by the lever arm distance at which the force is applied.
What describes the distance from the applied force to the fulcrum?
The distance from the applied force to the fulcrum is called the effort arm or lever arm. It is the perpendicular distance between the line of action of the force and the fulcrum in a lever system. The length of the effort arm affects the mechanical advantage of the lever.
How does the lever arm work?
The lever arm is the perpendicular distance between the pivot point of a lever and the line of action of a force applied to it. It determines the torque produced by the force acting on the lever. A longer lever arm results in a greater torque for the same amount of force applied.
What class lever increases the distance of the force?
A class 2 lever increases the distance of the force because the effort arm is longer than the resistance arm. This type of lever allows for more force to be applied over a greater distance, making it easier to move a load.
THE distance from the fulcrum to the resistance force in a lever is called the?
The distance from the fulcrum to the resistance force in a lever is called the load arm or effort arm. This measurement helps determine the mechanical advantage of the lever system and how much force is needed to balance or move a load.
Is a trebuchet a Force Magnifier or a Distance Magnifier?
A trebuchet is a distance magnifier because it allows a small force applied over a long distance to launch a projectile over a much greater distance. The long lever arm in a trebuchet creates a mechanical advantage that increases the distance the projectile can travel.
How does the input arm of a lever decreases the force needed to move an object?
The input arm of a lever acts as a longer lever arm, increasing the distance over which the force is applied. This results in a mechanical advantage, allowing the same input force to exert a greater output force on the object being moved. By increasing the distance from the pivot point, the lever allows for the force to be distributed over a larger distance, making it easier to move the object.
What is a lever's effort arm?
It is the part of a lever, where external force is applied in order to do work.
How do you calculate a lever's mechanical advantage?
From the design of the lever (on paper), the mechanical advantage is effort arm/load arm which means Distance from pivot to the applied force/distance from pivot to the load The result of that is that the forces will have the reciprocal ratio, and the input force to the lever will be the output force/the Mechanical Advantage .
What simple machine can increase distance?
A lever can increase the distance over which a force is applied. By using a longer lever arm, the input force can be spread over a larger distance to achieve a greater output distance.
