A screwdriver with a 1-cm shaft and a 4-cm handle is used to tighten a screw, what is the ima?
If those are both radii or diameters, the answer is 4.
Do you see why?
Do you know what ima stands for?
ideal mechanical advantage. That is the answer that I got too. It seemed to easy?! Thank you!!
To calculate the IMA (Ideal Mechanical Advantage) of a screwdriver, we can use the formula:
IMA = Length of the handle ÷ Length of the shaft
In this case, the length of the handle is 4 cm, and the length of the shaft is 1 cm. Plugging these values into the formula, we have:
IMA = 4 cm ÷ 1 cm
Therefore, the IMA of the screwdriver is 4.
To determine the IMA (Ideal Mechanical Advantage) of a simple machine like a screwdriver, we need to understand its basic principles. The IMA of a screwdriver is calculated by dividing the length of the handle by the length of the shaft.
In this case, the length of the handle is given as 4 cm, and the length of the shaft is given as 1 cm. Therefore, the IMA can be calculated as follows:
IMA = Length of handle / Length of shaft
= 4 cm / 1 cm
= 4
Hence, the Ideal Mechanical Advantage (IMA) of the screwdriver in this scenario is 4.
