The uniform cantilever carries a uniformly distributed load w and is supported on a rigid knife edge at the end D.



Suppose P is the force on the support at D.


Then we regard Figure(i) as the superposition of the effects of P and w acting separately.

If w acts alone, the deflection at D is given by equation, and has the value

If the reaction P acted alone, there would be an upward deflection

at D. If the support maintains zero deflection at D,
