and therefore its leverage is less. A passenger 

 will, in fact, be a convenient weight for the 

 purpose. 



In Fig. i, if the passenger's centre of gravity 

 over A is half as far behind the hub over C 

 as B is in front of it, B being the point at which 

 the jinrikisha man applies a part of his weight, 

 it is obvious that the leverage at B is twice

as great as that at A. If, therefore, the man 

 and his passenger be of the same weight, half 

 the man's weight at B balances all the passenger's 

 weight at A. But if half the man's weight is 

 pressing on the shafts at B, there is only half 

 left to be carried by his legs. This is a great 

 relief. On the other hand, the extra work 

 of drawing the passenger's weight and half 

 of his own, on light wheels over a good road, 

 is very small, and by no means counterbalances 

 the gain of having his legs relieved of half 

 his own weight. Thus it is actually easier 

 to draw his jinrikisha loaded than empty.
