What is the equation for mechanical advantage?
Mechanical Advantage = MMF / MRF
What does it mean to have a mechanical advantage?
There needs to be less muscle force compared to resistive force to create equal torque.
When is there a mechanical advantage?
MMF / MRF > 1
or
MMF > MRF
What does it mean to have a mechanical disadvantage?
More muscle force than resistive force to produce equal torque.
When is there a mechanical disadvantage?
MMF / MRF < 1
or
MMF < MRF
What is the advantage of mechanical advantage?
Less muscle force is needed to move an object.
What is a disadvantage of mechanical advantage?
An object will not move as far or as fast.
