Mechanical disadvantage
#ALevel #Physics looking at Mechanical disadvantage in a knee/elbow joint, from a Lamb Joint to @pascoscientific tension protractor to measure the forces at different lengths from the pivot. #iteachphysics #Science #STEM This lesson works well in Biology as well so the studemts doing both subjects benefitted.
