A is a simple machine with a fulcrum an effort arm and a resistance arm?
a lever
What is the length of effort arm divided by length of resistance arm?
Ideal Mechanical Advantage
What is the mechanical advantage of a lever with an effort arm of 16cm an a resistance arm of 2cm?
4
What is the formula for lever?
(AMA / IMA)100 Where AMA represents the actual mechanical advantage and IMA represents the Ideal Mechanical advantage. AMA = Fr/Fe where Fr equals the force of the resistance from the fulcrum, and Fe equals the force of the effort. IMA = De/Dr where De equals the Distance of the effort from the fulcrum and Dr equals the distance of the resistance from the fulcrum
What is the mechanical advantage of a lever with a resistance arm of 1.5 feet and an effort arm of three feet?
If a first class lever with a resistance arm measuring 2 feet and an effort arm measuring 8 feet are being used, what's the mechanical advantage
Which lever would have more mechanical advantages than one with a resistance arm of 3 inches and an effort arm of 6 inches?
a lever with an effort arm of 2 inches
What A lever has a resistance arm of 5 feet and an effort arm of 6 feet What measurement can be changed to increase the mechanical advantage of the lever?
increase the effort arm to 8 feet
How does Fixed Pulleys work?
They put a rope over one axle, and attach the other end to the weight, and this increases the distance. The formula for a fixed pulley is length of effort arm ------------------------- length of resistance arm recommend please
What kind of lever has a fulcrum resistance arm and effort arm?
first class levers actually in front of the effort and resistance forces
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
What is the formula to find resistance force?
Work force plus effort force
What part of LEVER?
the fulcrum, load and effort The three parts of a lever , fulcrum, resistance arm and effort arm, work together to make it possible to lift a weight using less force ...
