Human Structures Set
● Build models that represent real life examples.
● Bring homework problems to life!

Human Arm Model

Students build a realistic arm model and directly measure the forces exerted by the biceps muscle (tension in supporting cord). Vary the length and angle of upper and lower arm, as well as the point of attachment of the muscle.

Support Structure allows the angle of the upper arm to be easily adjusted.

Load cell represents the biceps muscle.Axle allows arm to pivot freely.

Construct all three models concurrently with this set.
Human Back Model


Model the forces acting on a human back. Vary all parameters including position of back muscle attachment and angle of the torso. Directly measure the force exerted by the back muscles.Load cells directly measure forces exerted on back model.

人体腿部模型
The leg model shown below uses a load cell for the quadriceps muscle to directly measure the force needed to support the leg at various angles.

Load cell represents quadriceps muscles.

Directly measure the force needed to support the leg at various angles.
