What is a smart material?
A material that reacts to an external stimulus or input to alter its functional or aesthetic properties.
What is the formula triangle involving load, mechanical advantage and effort?
Mechanical advantage effort
Distance moved = distance a
—————–
distance b
X distance a moved
😀
Velocity ratio = distance moved by effort DIVIDED BY distance moved by load
