A calculator and a formula for moments: Like distance from fulcrum x force = distance from fulcrum x force and I think mechanical advantage is the ratio of forces - for a lever for example where you need less force to exert a big force when for example, you wedge a crow bar in the side of the door to try and effect a break in

What two things you you need to know to calculate mechanical advantage?

To calculate mechanical advantage, you need to know the effort force applied to the machine and the resistance force it is able to overcome. By dividing the resistance force by the effort force, you can determine the mechanical advantage of the machine.


A lever is used to lift a 50 kg object at a constant speed if the applied force exerted on the lever is 100N what is the mechanical advantage of the lever?

The weight of the 50 kg object is (50 x 9.8) = 490 newtons.In order to lift the object with a force of 100 N, you need a mechanical advantage of 4.9 .That's the net mechanical advantage of the lever system, including all of its friction losses.


What do you need to know to calculate mechanical advantages?

To calculate mechanical advantage, you need to know the input force and the output force. Mechanical advantage is calculated by dividing the output force by the input force. It provides a measure of how much a machine multiplies force or changes the direction of force.


What do you need to know to calculate the machinical advantage of a compond machine?

To calculate the mechanical advantage of a compound machine, you need to know the input force applied to the machine, the output force produced by the machine, and the distance over which the input and output forces are exerted. By comparing the input force to the output force, you can determine the mechanical advantage of the compound machine.


What is the disadvantage of a first class lever?

One disadvantage of a first-class lever is that the effort arm may need to be longer than the resistance arm to achieve mechanical advantage, making the lever system less compact or cumbersome to use compared to other lever types.

What do you need to know to calculate the mechanical advantage of a compound machine?

To calculate the mechanical advantage of a compound machine, you need to know the input force applied to the machine and the output force obtained from the machine. Additionally, you will need to understand how the individual simple machines within the compound machine are connected or arranged to determine the total mechanical advantage.

When calculating the mechanical advantage of a lever what two pieces of information are needed?

You need to know the length of the lever and the location of the fulcrum along that length. The ratio of the lengths on either side of the fulcrum will determine the ratio of forces at either end. The length of the lever will dictate the total force possible. For a lever of length L divided into lengths a and (L - a) by the fulcrum (where a is the length of the lever between the fulcrum and the object you want to apply force to), the mechanical advantage will beM.A = (L-a)/aThe longer the lever, the bigger you can make the numerator of that fraction while keeping a unchanged.


What effort force would be needed to lift a load of 150 N with a lever system that has a mechanical advantage of 3.5?

Well lets see. I suppose that a ballance is a lever advantage of one: which of course is the same on both sides; that is no advantage. So a lever of an advantage of two, is, half of that same force on the other side. So the answer is (half of 150) or 75N.


Do you need a short lever or long lever to lift something easier?

A long lever will make it easier to lift something because it allows you to exert more force over a greater distance, reducing the amount of force needed. Short levers require more effort as they provide less mechanical advantage.


Is it good to have a high mechanical advantage?

It may be good in some cases. A high mechanical advantage comes at a cost - you need to apply less force, but you need to apply it over a greater distance.


WHAT ARE THE Disadvantages OF CLASS 1 LEVER?

The main disadvantage of a Class 1 lever is that the output force is generally less than the input force, which can make it less efficient for lifting heavy loads. Additionally, the lever arm lengths need to be carefully adjusted to achieve the desired mechanical advantage, which may require more precise construction and control.


When using a lever do you do less work than if you lifted the object without the lever?

No, the amount of work done will be the same. The lever provides mechanical advantage by multipling force times distance applied. A 1 kg object will need about 10 Joules of work to lift it up a vertical distance of 1 meter, no matter whether it is lifted straight up, or over a greater distance such as up a ramp, or with a lever.
