Question

The drawing shows a lower leg being exercised. It has a 46-N weight attached to the foot and is extended at an angle with respect to the vertical. Consider a rotational axis at the knee.

The drawing shows a lower leg being exercised. It has a 46-N weight attached to the foot and is extended at an angle theta with respect to the vertical. Consider a rotational axis at the knee. (a) When theta = 90.0degree, find the magnitude of the torque that the weight creates. = ? N m (b) At what angle theta does the magnitude of the torque equal 13 N m? = ? degree

Explanation / Answer

a) = rF = 0.55 x 45 = 24.75 N m

b) 13 = rFsin

13 = 0.55 x 45 x sin

= 31.68
