Question

Why are forces in our joints several times larger than the forces exerted on the outside world with our limbs? Can these forces be even greater than muscle forces?

a) Joints are less efficient than muscles.
b) Joints amplify forces, and yes, they can be greater than muscle forces.
c) Joints have lower mechanical advantage.
d) Muscle forces are always greater.

Answer 1

The forces in our joints are larger than the forces we exert on the outside world with our limbs because joints amplify forces. These forces can be greater than muscle forces.

Step-by-step explanation:

The forces in our joints are several times larger than the forces we exert on the outside world with our limbs because joints amplify forces. The forces in our joints are larger than the forces we exert on the outside world with our limbs because joints amplify forces. These forces can be greater than muscle forces.

Yes, these forces can be greater than muscle forces. When muscles contract, they can exert force on the joints, causing a mechanical advantage and amplifying the force exerted. The forces in our joints are larger than the forces we exert on the outside world with our limbs because joints amplify forces. These forces can be greater than muscle forces.
