Because gravitational potential energy equals mass•acceleration due to gravity•height (mgh), we can calculate the potential energy by multiplying 80•9.8•8850, which results in 6,938,400 j.

An output gear has 10 teeth and an input gear has 40 teeth. What is the mechanical advantage of gear combination? Is force or sp

yKpoI14uk [10]

Answer:

Mechanical advantage: 4. Speed is multiplied

Explanation:

The mechanical advantage of gear combination is

$MA = \frac{N_i}{N_o}$

where

$N_i$ is the number of teeth in the input gear

$N_o$ is the number of teeth in the output gear

Here we have

$N_i = 40\\N_o = 10$

So we find

$MA = \frac{40}{10}=4$

In this example, it is the speed to be multiplied: the speed of the output gear is 4 times larger than the speed of the input gear. In fact, the mechanical advantage can be rewritten as

$MA= \frac{\omega_o}{\omega_i}$
