Mechanisms that will achieve the highest torque output possible.

In the four gear example, determine the following:

a) All the mechanisms that will achieve the highest torque output possible.
b) All the mechanism combinations that will achieve the greatest rpm output possible.
c) List all the mechanisms that will be able to handle the above scenario of moving a load of 5 lbs located at a perpendicular distance of 8 inches.
d) List all the mechanisms that will be able to handle a 20 lb weight located at a perpendicular distance of 8 inches.
Write a brief report format for this report.
