Answer:
IMA = 2
Explanation:
Given the following data;
Resistance gear = 54 teeth
Effort gear = 23 teeth
To find the ideal mechanical advantage (IMA);
IMA = number of teeth on the resistance gear/number of teeth on the effort gear
Substituting into the equation, we have;
IMA = 54/23
IMA = 2.35 ≈ 2
Therefore, the ideal mechanical advantage (IMA) of this two-gear system is 2.
