שאלה קטנה על המומנט
תעזרו לי בבקשה The moment of inertia of the forearm about the axis of rotation of the elbow is 0.094 kg·m2. Suppose that the forearm drops from a 52.6° elbow angle to a 115.6° elbow angle under the influence of gravity while a mass of 4.80 kg is being held at a distance d = 0.30 m from the center of rotation of the elbow. Assume that the mass acts like a point mass. Make a simplifying assumption that the angular acceleration due to gravity is independent of joint angle and is equal to -19.0 rad/s2. Find the minimum torque that the flexor muscles must generate to stop the movement of the elbow within 0.130 s after it reaches 116°.
