What is the formula used to calculate mechanical advantage?
Mechanical advantage=load/effort
Why is the actual mechanical advantage of an inclined plane alwaysess than the theoretical mechanical advantage?
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many people would call an estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less.

How do you find the mechanical advantage of a wheelbarrow?
Mechanical advantage= effort arm length/ load arm length For Example Effort arm=120 cm Load arm length= 40 cm MA-120/40 = 3
What are the four parts of the lever?
load arm, effort arm, load, effort, fulcrum!
An inclined plane reduces the effort by?
Lesser the height of inclined plane, and more the length of it, More will be the mechanical advantage of inclined plane i.e less effort would be applied.
What is the mechanical advantage of a lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
What is a mechanism of a lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
What is the relationship between distance from the fulcrum and the mechanical advantage of a first class lever?
The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum
How do you calculate the mechanical advantage of a first class lever?
It's the ratio of the distances effort-fulcrum/load-fulcrum.
When is mechanical advantage increased by a first class lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
What do you need to know to calculate the mechanical advantage of a compound machine?
torque in * input rpm/output rpm = torque out
What is the mechanical advantage of a first-class lever in which the fulcrum is 10 inches from the resistance and 40 inches from the effort?
answer is 4
Why is a nutcracker is second class?
A lever that has the load between the fulcrum and the effort is known as a second order lever. Once again, the further away the effort is from the fulcrum and the load the greater the mechanical advantage of the lever.
What happens when the fulcrum is further from the load?
The closer the load is to the fulcrum the greater the mechanical advantage. The closer to the fulcrum, the less the load moves when the lever is used.
What would increase the mechanical advantage of a first class lever?
Move the fulcrum (pivot) farther from the effort and closer to the load.
What is the mechanical advantage of a first class lever in which the fulcrum is 10 inches from the resistance and 40 inches from the effort?
answer is 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
