Using a crowbar you apply an effort force of 30 N to pry open a window that has resistance force of 600 N so What is the mechanical advantage MA of the crowbar?

MA= Resistance force / Effort force
= 600N / 30 N
MA = 20N

How do you calculate the mechanical advantage of gears?
effort divided by load or vice versa
How can you increase mechanical advantage of a gear system?
A mechanical advantage occurs when a tool such as a hammer is used that increases the amount of force being applied without increasing the effort of the person using the tool. To increase mechanical advantage, you could use a bigger hammer to increase output force.
How does a greater mechanical advantage benefit a machine?
Lever: A lever consists of a rigid bar (the lever arm) that pivots around a fixed point called the fulcrum. By applying a force at one end of the lever, you can lift or move a load at the other end. Depending on the positions of the force and load relative to the fulcrum, levers can amplify force or distance. Pulley: A pulley is a wheel with a groove that holds a rope, cable, or belt. When you pull on one end of the rope, it moves the load attached to the other end. Fixed and movable pulleys can change the direction of force or provide a mechanical advantage, making it easier to lift heavy objects. Wheel and Axle: A wheel and axle consist of a larger wheel connected to a smaller axle. When force is applied to the wheel, it generates rotational motion that can be used to move loads. The mechanical advantage depends on the ratio of the wheel's radius to the axle's radius. Inclined Plane: An inclined plane is a flat surface that is sloped. By sliding an object along the inclined plane, you can exert a smaller force over a longer distance to move the object to a higher or lower elevation. This reduces the force required to lift the object vertically. Wedge: A wedge is a double-inclined plane used to split or separate objects. When you apply force to the thick end of the wedge, it generates a large force at the thin end, making it useful for cutting, splitting, or prying. Screw: A screw is an inclined plane wrapped around a cylindrical shaft. When you rotate the screw, it moves along its threads and can lift or hold objects. Screws provide both a mechanical advantage and a way to generate motion over a distance.
What is load force?
The load force is applying a force to move or hold an object that has weight.
What is meant by mechanical?
From Wikipedia, Mechanical is often used as a general term to distinguish from another class of item. Mechanical may mean:Mechanical engineering, a branch of engineering concerned with the application of physical mechanicsMachine, especially in opposition to an electronic itemMechanical watch, utilizing a non-electric mechanismMechanization, using machine labor instead of human or animal laborAutomation, using machine decisions and processing instead of humanManufactured or artificial, especially in opposition to a biological or natural component
The ratio of resistance force to effort force?
The ratio of resistance force to effort force is a mechanical advantage.
If you have to apply 40 N of force on a crowbar to lift a rock that weights 400 N what is the actual mechanical advantage of the crowbar?
It would have a mechanical advantage of 20, thus dividing the resistance force of 600N by the effort force of 30N.
Is it true that the ideal mechanical advantage or IMA of a machine is the resistance distance divided by the effort distance?
resistance,effort
What is the formula for determine ideal mechanical advantage?
the formula for determing ideal mechanical advantage is effort divided by resistance
How mechanical advantage is expressed?
the resistance force multiplied by the effort force
What if the effort is 30 cm and a resistance is 3 cm. What is the mechanical advantage?
10
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
How do the three classes of levers work?
Class 1: Fulcrum in the middle: the effort is applied on one side of the fulcrum and the resistance on the other side, for example, a crowbar or a pair of scissors.Class 2: Resistance in the middle: the effort is applied on one side of the resistance and the fulcrum is located on the other side, for example, a wheelbarrow, a nutcracker, a bottle opener or the brake pedal of a car. Mechanical advantage is greater than 1.Class 3: Effort in the middle: the resistance is on one side of the effort and the fulcrum is located on the other side, for example, a pair of tweezers or the human mandible. Mechanical advantage is less than 1.
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
Is effort diastance is equal to the resistance distance?
You can make any relationship you want between the effort distance and the load (resistance) distance. If you make them equal, then your lever has no mechanical advantage.
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
