The handle of a car jack is moved 75 cm
and the car is lifted 2.5 cm. What is the
ideal mechanical advantage of this car jack?
30
The ideal mechanical advantage (IMA) of a car jack can be calculated using the formula:
IMA = distance moved by the handle / distance lifted by the load
Given that the handle is moved 75 cm and the car is lifted 2.5 cm, we can substitute these values into the formula:
IMA = 75 cm / 2.5 cm
Simplifying the division, we find:
IMA = 30
Therefore, the ideal mechanical advantage of this car jack is 30.
The handle of a car jack is moved 75 cm and the car is lifted 2.5 cm. What is the IMA?
Well, that car jack is really putting in the effort, isn't it? Let's do some math here. The ideal mechanical advantage (IMA) of a machine is the ratio of the distance a force is applied to the distance the load moves. So, in this case, the handle of the car jack is moved 75 cm, and the car is lifted 2.5 cm.
Now, to find the IMA, we just divide the distance the handle is moved by the distance the car is lifted. So, 75 cm divided by 2.5 cm gives us an IMA of... *drumroll* ... 30! That car jack sure knows how to make those centimeters count! Keep on jacking, you magnificent machine!
To find the ideal mechanical advantage (IMA) of a car jack, we need to divide the distance the handle is moved by the distance the car is lifted.
In this case:
Distance moved by the handle = 75 cm
Distance the car is lifted = 2.5 cm
So, the IMA = Distance moved by the handle / Distance the car is lifted
= 75 cm / 2.5 cm
= 30
Therefore, the ideal mechanical advantage of this car jack is 30.
