If the input force on a simple machine is 2 N and the output force is 4 N, what is it’s mechanical advantage?
2 answers:
Explanation:
Given that,
Input force on a simple machine, F = 2 N
The output force on a simple machines, F' = 4 N
The ratio of the output force to the input force of any simple machines is called its mechanical advantage. Mathematically, it is given by :
Putting the value of F and F' in above equation. We get :
m = 2
So, the mechanical advantage of the simple machines is 2. Hence, this is the required solution.
Answer:
Mechanical advantage, m = 2

Answer:
2000 W
Explanation:
First of all, we need to find the output voltage in the transformer, by using the transformer equation:
where here we have
V1 = 200 V is the voltage in the primary coil
V2 is the voltage in the secondary coil
N1 = 250 is the number of turns in the primary coil
N2 = 500 is the number of turns in the secondary coil
Solving for V2,
Now we can find the power output, which is given by
P = VI
where
V = 400 V is the output voltage
I = 5 A is the output current
Substituting,
P = (400 V)(5 A) = 2,000 W
