if a person exerts 250n force to lift a 1250n object using a simple machine, what is the mecahnical advantage of the machine
Using the Law of the lever
MA =F2/F1 =1250/250 =5
Ah, lifting heavy objects, a classic exercise in defying gravity! Now, let me calculate the mechanical advantage so we can fully appreciate the wonders of this simple machine.
To find the mechanical advantage, we can use the formula:
MA = Load / Effort
In this case, the Load is 1250N (the weight of the object) and the Effort is 250N (the force exerted). Let's plug those values in:
MA = 1250N / 250N
And after some mathematical magic:
MA = 5
Voila! The mechanical advantage of the machine is 5. So, for every 250N of force applied, it allows you to lift a hefty 1250N object. Using this simple machine, you'll be feeling as strong as a superhero. Just be careful not to accidentally chuck the object into space! 😄
To determine the mechanical advantage of a machine, we can use the formula:
Mechanical Advantage (MA) = Output Force (Fout) / Input Force (Fin)
In this case, the output force is the force exerted to lift the object, which is 250 N, and the input force is the weight of the object, which is 1250 N.
Using the formula, we can calculate the mechanical advantage:
MA = 250 N / 1250 N
MA = 0.2
Therefore, the mechanical advantage of the machine is 0.2.
To determine the mechanical advantage of a simple machine, we can use the formula:
Mechanical Advantage = Output Force / Input Force
In this case, the input force is the force exerted by the person (250 N), and the output force is the weight of the object (1250 N).
So, substituting the values into the formula:
Mechanical Advantage = 1250 N / 250 N
Simplifying:
Mechanical Advantage = 5
Therefore, the mechanical advantage of the machine is 5.
