A screwdriver with the one similar shaft in a 4 cm handle is used to tighten a screw the mechanical advantage is
To calculate the mechanical advantage of a screwdriver, we need to know the length of the effort arm (handle) and the length of the resistance arm (shaft). The mechanical advantage (MA) of a screwdriver can be calculated using the following formula:
MA = Length of Effort Arm / Length of Resistance Arm
In this case, we are given that the handle (effort arm) is 4 cm long. However, we need to determine the length of the resistance arm (shaft) to calculate the mechanical advantage accurately.
To measure the length of the resistance arm (shaft), you can follow these steps:
1. Take a ruler or tape measure.
2. Place the screwdriver on a flat surface.
3. Measure the length of the shaft from the point where it contacts the surface to the end of the shaft using the ruler or tape measure.
Once you have the length of the resistance arm (shaft), you can substitute the values into the formula to calculate the mechanical advantage.
