he drawing shows a lower leg being exercised. It has a F = 48 N weight attached to the foot and is extended at an angle with respect to the vertical. Consider a rotational axis at the knee.



At what angle does the magnitude of the torque equal 13 Nm?



He drawing shows a lower leg being exercised. It has a F = 48 N weight attached to the foot and is extended atperforming arts



And the drawing is...



To determine the torque we need force (F) and an arm (R)



T=R x F



or



T=|R| |F| sin(angle between R and F)



angle = arcSin(T/(|R| |F| )) So what is R?
