Answer :
The total ratio of the drive is 9.58:1.
What are ratios?
- A relationship between two quantities that are typically stated as the product of their respective quotients is known as a ratio.
- The ratio formula is given as a:b = a/b for any two quantities, let's say a and b.
Given ratios of the three separate stages of a gear reduction drive are 3:1,2.38:1 and 4.2:1.
To find the total ratio of the drive we have to add the respective ratios.
When the denominator of the ratios are same, as in this case we just have to add the numerators to obtain the result.
Total ratio of the drive = 3:1 + 2.38:1 + 4.2:1 = 9.58:1
So, the total ratio of the drive is 9.58:1.
