1. The PASCO human arm model is configured such that
the cord representing the bicep is perfectly vertical and
the forearm is at 90° (in the figure to the right, the cord
is not quite vertical). A mass of 100 g is attached to the
hand. Draw a free-body diagram on the figure to the
right showing all forces which act on the forearm.
The force of the bicep F on the arm
The force of the humerus FH on the arm
The weight of the forearm W
The mass in the hand Wm
100 g
Be careful to draw the force vectors with tails beginning at the point where the force is actually
applied to the forearm.
2. Consider the free body diagram below. Determine the perpendicular component F̟ of the
force F exerted by the biceps brachii on the forearm. Use the fact that cos 0 = H/B to write
this component directly in terms of the humerus length H and the biceps length B.

3. If the forearm is in equilibrium, then there is no angular acceleration and therefore the sum of
the torques applied to the forearm must be…
Three masses K, L and M of
magnitudes 20 kg, 18 kg and 16 kg are
attached rigidly to the shaft. The
masses are rotating in the same plane.
The corresponding radii of rotation are
160 mm, 190 mm and 130 mm
respectively. The angle made by the
mass K with horizontal is 50° and the
angles between masses K to L 90°
and L to M 170° respectively. Find the
magnitude of the balancing mass if its
.radius of rotation is 200 mm
The rope shown in the figure below is wound around a cylinder of mass 4.0 kg and I = 0.020 kg m2, about the cylinder axis. If the cylinder rolls without slipping, what is the linear acceleration of its center of mass? What is the frictional force? Use an axis along the cylinder axis for your computation.
What happens if the frictional force between table and cylinder is negligible? Choose any axis for your computation.
