The drawing shows a lower leg being exercised. It has a 49-N weight attached to the foot and is extended at an angle 0 with respect to the vertical. Consider a rotational axis at the knee. $\left(\text { a ) When } \theta=90.0^{\circ}\right.$ find the magnitude of the torque that the weight creates. (b) At what angle $\theta$ does the magnitude of the torque equal 15 $\mathrm{N} \cdot \mathrm{m}$ ?
The drawing shows a lower leg being exercised. It has a $49-\mathrm{N}$ 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 $\theta=90.0^{\circ}$, find the magnitude of the torque that the weight creates. (b) At what angle $\theta$ does the magnitude of the torque equal $15 \mathrm{N} \cdot \mathrm{m} ?$
The drawing below shows a lower leg being exercised. The lower leg has a 49N weight attached to the foot and it is extended at an angle ? with respect to the vertical. The lower leg rotates about the axis of the knee as shown in the diagram below. At what angle ?, does the magnitude of the torque exerted by the 49N weight about the axis of the knee equal 25 Nm?
