What simple machine has a bar that is free to pivot about a fixed point?
I think its a lever!?
What is the ratio of Two triangles that are similar and have a ratio of similarity of 310 what is the ratio of their areas?
If the ratio of similarity is 310, then the ratio of their area is 96100.
What is eqivalent ratio?
an eqivalent ratio is an ratio that is equal or you can simplfiy it
What does a lever look like?
A lever is like a pole with a fulcrum. Here is a picture: ---------------------- ^ the triangle, which is supposed to be the fulcrum, is supposed to be attached to the k=line, which is the lever. Hope I helped! --Contributor ; )
What is the definition of unit ratio?
Unit Ratio- a ratio that has a denominator of 1
What is lever arm ratio?
Divide the length of the force arm by the length of the resistance arm.
What is the relationship between distance ratio and mechanical advantage?
The mechanical advantage is equal to the input distance divided by the output distance. This means that the mechanical advantage is inversely proportional to the distance ratio; as the distance ratio increases, the mechanical advantage decreases.
What is the efficiency formula of lever?
The efficiency of a lever can be calculated using the formula: Efficiency = (output force × output distance) / (input force × input distance) * 100%. It represents the ratio of the output work done by the lever compared to the input work applied to the lever.
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.
Which tyoe of lever always increases mechanical advantage?
A first-class lever always increases mechanical advantage, as the effort arm is longer than the load arm. The mechanical advantage is determined by the ratio of the lengths of the two arms of the lever.
What is the increase in work done by a lever called?
The increase in work done by a lever is called mechanical advantage. It represents the ratio of the output force exerted by the lever to the input force applied to it. A lever with a higher mechanical advantage requires less input force to lift an object.
What is the machanical advantage we gain by using a lever?
The mechanical advantage gained by using a lever is determined by the ratio of the distance from the fulcrum to the point where the input force is applied compared to the distance from the fulcrum to the point where the output force is applied. This ratio helps multiply the input force to exert a greater output force, making it easier to lift or move heavy objects using a lever.
How do you calculate the mechanical advantage of a first class lever?
It's the ratio of the distances effort-fulcrum/load-fulcrum.
How do place a Land Rover in 4x4 mode?
most land rovers are permenant 4x4 they usually have a second lever to switch between high and low ratio some also have a separate diff lock lever.
What is meant by velocity ratio of lever is 1?
When the velocity ratio of a lever is 1, it means that the effort arm is equal in length to the load arm. This implies that the distance moved by the effort is equal to the distance moved by the load, resulting in a balanced system.
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 .
How is the mechanical advantage of a lever determined?
The mechanical advantage of a lever is determined by dividing the length of the lever on the effort side (distance from the fulcrum to the point where the effort is applied) by the length on the resistance side (distance from the fulcrum to the point where the resistance is located). This ratio provides insight into how much force is gained or lost when using the lever.
