The pedal-chainwheel unit of a bicycle is shown in the figure. The left foot of the rider exerts the 40-lb force, while the use of toe clips allows the right foot to exert the nearly upward 20-lb force. Determine the equivalent force-couple system at point O. Also, determine the equation of the line of action of the system resultant treated as a single force R. Treat the problem as two-dimensional.
