- The uniform solid block in the figure has mass 21.3 kg and edge lengths a=0.754 m, b = 1.33 m, and c = 0.0662 m. Calculate its rotational inertia about an axis through one corner and perpendicular to the large faces. Number Mo Units Rotation axisA soccer player extends her lower leg in a kicking motion by exerting a force with the muscle above the knee in the front of her leg. Suppose she produces an angular acceleration of 32.5 rad/s2 and her lower leg has a moment of inertia of 0.75 kg⋅m2 . What is the force, in newtons, exerted by the muscle if its effective perpendicular lever arm is 2.1 cm? F =For each question, use degrees NOT radians. Healthcare professionals, when measuring range of motion (ROM) and isokinetic strength, use degrees - so this assignment will use answers in degrees as well. A person is laying on their stomach doing a hamstring curl. They go from fully extended (0o) to 130o of flexion. What is their angular displacement if the person is on their stomach with their head facing left (feet pointing right)?
- To develop muscle tone, a woman lifts a 4.00 kg weight held in her hand. She uses her biceps muscle to flex the lower arm through an angle of 60.0°. (a) What is the angular acceleration (in rad/s2) if the weight is 24.0 cm from the elbow joint, her forearm has a moment of inertia of 0.250 kg · m2, and the net force she exerts is 650 N at an effective perpendicular lever arm of 2.20 cm? (Ignore gravity) (b) How much work (in J) does she do?A 2.00-m long rod is hinged at one end. The rod is initially held in the horizontal position, and then released as the free end is allowed to fall. (a) What is the angular acceleration as it is released? (b) What is the angular acceleration when it reaches the vertical position? (c) Which position has the maximum angular velocity (vertical or horizontal)? (d) Which position has the maximum angular acceleration (vertical or horizontal)? (The moment of inertia of a rod about one end is ML2/3.)In the figure, the disk is at rest, homogeneous, and weighs 50 lb. If a horizontal force P is applied to its center of mass at G, and it experiences friction as shown, determine the angular acceleration of the disk and the acceleration of point G.
