What type of lever class is a seesaw?
A seesaw would be a Class 1 lever. This is because the fulcrum(also known as a pivot) is in the middle of the load and effort.
How heavy is concrete per cubic meter?
Concrete weighs about 150 pounds per cubic foot. Can't do the math but that is about 4500 pounds.
What are two ways machines make work easier?
Machines make work easier because they help to increase productivity. An example of a machine is a forklift. Forklifts allow workers to move more materials at one time which lowers the amount of time it takes to move materials.
What are the two families of simple machines?
You probably mean the two CLASSES of simple machines.There are six simple machines:Inclined PlaneWedgeScrewPulleyWheelLeverThe two classes of simple machines are:1. The simple machines that deal with vector quantities like velocity and force(the inclined plane, the wedge and the screw).2. The simple machines that deal with torque (the force to rotate an object around an axis, pivot, etc.) like the pulley, the wheel, the lever.You would think a screw falls into the torque class, but it's classified as a helical inclined plane.Read more: http://wiki.answers.com/What_are_the_two_classification_of_simple_machines#ixzz1mZkiS0qr
What would life be without simple machines?
Do you mean technological development? Then the answer is no. All complex machines are made up of simple machines in various combinations. Without the one, you can't have the other. The world would go on, of course, but the technological complexities of its modern civilizations could not exist without simple machines.
How does the position of the fulcrum and the location of the load affect the amount of effort force you must exert to lift the load?
To do this you first have to calculate your ideal mechanical advantage (IMA). The IMA is equal to the effort distance (the distance from the fulcrum to where you will apply the effort) divided by the load distance (the distance from the fulcrum to the load). You can then set your IMA equal to your acutal mechanical advatage (AMA) which assumes 100% efficiency. The AMA is equal to the load force (the weight of what you are lifting) divided by the effort force (the # you are looking for). So, for example, if your IMA is 5 and your load force is 500 lbs: 5=500/effort force. Therefore the effort force would be 100 pounds.
What force would the scale exert on a 53 kg person standing on it?
On earth, the force would be 116.845 pounds (rounded). That force is exactly equal and opposite to the person's weight. If the sum of the forces on the bottom of his feet were not zero, then he would be accelerating vertically.
Why is friction a force?
Friction is considered a force because it acts on an item and causes changes, which is what a force is. Nothing would happen if the item was in an area where friction was not possible or if friction was where an object was not since they need each other to exert external effort.
What do you call a force that you exert away from you?
Mass
If the effort distance is increased by an inclined plane will the effort force decrease?
actually, the effort force would be decreasing, and the effort distance would be increasing!
How much force does one exert when lifting an object?
The force would be the weight of the object.
What liquid would exert a greater buoyant force?
my liquids
What is the ration to resistance force to effort force?
The effort required would be proportional to the resistance.
What would be a synonym of working your butt off?
endeavor, labor, toil, exert, travail, effort.
A 150 pound man is standing on a lever one foot from the fulcrum. How much effort must be used to lift the man if the effort is applied six feet from the fulcrum?
6 x 150 pounds. 900 pounds of force would have to be applied.
Is the force that objects exert on each other because of their masses?
That would be "Gravity".
If you were in orbit how much force would you exert on a scale?
In orbit your weight is zero.
