What is the effect on the effort force used when the length of the effort arm is decreased?
The force you are referring to is called torque. here is an example: you have 2 wrenches, one with a short handle and the other with a long handle, and 2 identical bolts. The force required for the longer wrench to turn the bolt is less than the force required for the short to turn the bolt. This is because the longer the handle the greater the Torque and therefore less force needs to be applied. summary: longer "effort arm"=more torque= less...

How do you calculate if the effort force was missing?
If you know the amount of work, and distance, set up an algebraic expression. For instance if the amount of work is 40, and the distance is 2 feet, and you let F= effort force, the equation is 2F=40. You solve by dividing by both sides by 2. So, the effort force is 20. ...
What is the mechanical advantage of a fixed and free pulley?
A fixed pulley does NOT multiply the effort force or have a mechanical advantage. It only changes the direction of the effort force. A free pulley multiplies the effort by two. this means the free pulley has a mechanical advantage of 2. information from: www.mhscience02.com ...

What two forces are involved when a machine is used to do work?
2 forces are always involved when using a machine. * Effort Force - FE - the force applied to a machine. * Resistance Force - FR -the force applied by a machine. ...

How many pounds of effort force does a lever have if it has an effort arm of fifteen units long and a resistance arm of 10 units and can lift a 3-pound weight?
It would require (3 X 10)/15 = 2 lb to lift the 3 lb weight. Actually, something a little greater than that. 2 lb is the force to balance it. (Obviously, the lever "has" no force. It requires the force to lift the weight.) ...

How do you calculate the effort force if the effort force is missing?
First of all, that will be the situation every time, because if the effort force isn't missing, then you have have no reason to calculate it. In order to calculate a missing piece of information, follow these steps: 1). Quit fretting and whining about the information you don't have. 2). Gather the information that you do have. 3). Gather all the equations and formulas you know that relate the information you do have to the item you're trying to find. 4). Select the best formula and...

On what factors does the effect of force depend?
The factor of a force depends on two things: 1. the amount of a force applied. The more the force applied the greater the effect. 2. the area on which the force is applied. The smaller the area the force is applied on, the greater the effect. ...
What 2 things affect the amount of friction when 2 surfaces are touching?
Force of friction = coefficient of friction + normal force The normal force is the force on the surface by the object that is perpendicular to the surface. This would mean that the angle of the surface and the acceleration of the surface would be taken into account. ...
