Part F Mechanical advantage is the ratio of output force to input force. In this part of the task, you'll explore mechanical advantage using a simulation in which you use a ramp (inclined plane) to put a crate into the back of a truck.

Open the inclined plane simulation. Keep all the default presets except for friction; set this to 0. To run the simulation, click on the crate and drag it up the ramp until the force arrow turns green, indicating that you're pulling with enough force to move the crate. Note that your actual mechanical advantage (Actual MA in the Outputs) is 2.24.

Reset the simulation, and return the friction to 0. How can you alter the ramp's length and height to increase its mechanical advantage? Does increasing the mechanical advantage make it harder or easier to push the crate up the ramp?

Explanation:

thats all you said

the amount of fabric used and the collar fitting and sleeve lenghts are the two options, that to me, make the most sense.

hope it ,

happy homework/ sutdy/ exam!
