Statics

Question 1

Statics

Answer 1

Constant velocity or not moving

Question 2

Static Equilibrium

Answer 2

Id angular acceleration is zero, the sum of torques must equal zero

Question 3

Solve this

Answer 3

Tm +
Tarmw -
Tw -
Sum = 0
Tm = Tarmw + Tw
Tm = (0.45)(45) + (0.4)(100)
Tm = 6.75 + 40
Tm = 46.75

Question 4

Statics - Assumptions

Answer 4

• Anatomical axis of rotation known
• One muscle group controlling the joint motion
• Muscle attachment sites known
• Line of action of muscle known
• Segment weights and COM known
• Friction is negligible
