Suppose you're designing the gearing system of the bicycle which will provide propulsion for a human-powered cargo hauler. The hauler consists of the bicycle plus three individual rolling carts which can be attached front-to-back behind the bicycle. The human rider must provide sufficient force to the pedals in order for the hauler to achieve the minimum acceleration necessary for safe operation on roadways. Your gearing system must ensure that the minimum acceleration can be provided to the hauler without exceeding the maximum force which can be repeatedly provided by a human rider without incurring injury. Assuming you know the minimum required hauler acceleration and maximum applied rider force, which of the following pieces of information are essential input for your design? (a) total length of the hauler, including the bicycle plus all three carts (b) the mass of the bicycle plus the mass of the three unloaded carts (c) the maximum cargo weight for each cart (d) the maximum weight for the human rider (e) all of the above (f) all except for answer (a)
