Answer:
The ideal mechanical advantage (IMA) is .
Step-by-step explanation:
The ideal mechanical advantage is the ratio of length of longer lever to that of shorter lever
IMA
Please refer to the image attached.
We could see that the the resistance load moves cm towards the fulcrum so the distance of resistance load from fulcrum
Now the as the effort force moves towards the fulcrum overall distance from the fulcrum to the effort force (load)
Plugging the values of the distances in IMA formula we can have.
IMA .
So the IMA of the fulcrum (simple machine)
Answer:
Length = 16 inches and width = 12inches
Step-by-step explanation:
A = 192 in² . The width is 4 + 1/2x. therefore let x = length
Area = LW
192 = x(4 + 1/2 x)
192 = 4x + 1/2x²
384 = 8x + x² Multiply each term by 2 to make a
384 + 16 = x² + 8x + 16 Complete the square
400 = (x + 4)²
± 20 = x + 4
20 = x + 4 or -20 = x + 4
20 - 4 = x or -20 - 4 = x
16 = x or -24 = x reject the negative amount
Length = 16
width = 4 + 1/2(16); 4 + 8 = 12
