What lever would have more mechanical advantage than one with a resistance are of 3 inches and an effort arm of 6 inches?
increase the effort arm to 8 feet
Why are levers useful?
A lever is a simple machine that changes the distance the force is applied over. It is helpful by since the force is applied over distance you can lift things. One example of this machine is a seesaw and a boat paddle. If we did not have this machine on a seesaw we would stay balance. Levers are devices that increase the force you use them with. Each lever has three main parts: the fulcrum, resistance arm, and effort arm.
How is it possible for a small force on one side of a lever to balance a large force on the other side?
the weight is put on the angle of the lever not the small force pushing it down
What is the name for the effect a force has when it is applied to one end of a lever and tries to turn the lever?
torque
Is friction a push force?
Friction is a push force. When one object pushes one direction on an object the other object pushes the opposite direction. The harder an object is pushed against another the more friction there is.
What the force that pushes on one arm of a lever?

What does it mean if a lever is at a mechanical disadvantage?
A lever at a mechanical disadvantage exerts a smaller force on the output arm than is exerted on the input arm; if you push with 10N on a lever with a disadvantage of 2, the other arm only exerts a 5N force. However, a lever with a mechanical disadvantage exerts the smaller force over a greater distance. Trebuchets are one example of a mechanically disadvantaged lever: the fairly small projectile doesn't need a huge force to propel it, and the greater distance afforded by the lever allows it to travel at great speed.
What kind of lever is toothbrush?
tooth brush is not a lever,because it has no fixed fulcrum from which one can separate the load arm and the effort arm.

What does the rocker arm in a car do?
Pushes the valve open. When the pushrod lifts up one end the other end pivots down and pushes the valve down.
Is friction a push force?
Friction is a push force. When one object pushes one direction on an object the other object pushes the opposite direction. The harder an object is pushed against another the more friction there is.
Which type of lever has the fulcrum locatd at one end and the effort force at the other?
a second-class lever
Is a force a lever?
No. A lever is a simple machine that redirects and multiplies the force applied to it. You press down on one end and whatever is on the other end goes up.
