How is it possible to increase the M.A. of the above lever without increasing its length?
Solution:  
The M.A. of the given lever can be increased by increasing the effort arm or decreasing the load arm.
(∵  M.A. of lever  =    Effort arm    Load arm  )\left( \because \; \text{M.A. of lever} \;=\; \frac{\; \text{Effort arm}\;}{\; \text{Load arm}\;} \right)
