it looks something wrong with F

Clear before ϕ

x hs Clear 1

... or use line( ) in ϕ

Define ϕ

x φ x x hs * :

Define hs and use ϕ

x hs x 0.5 > (:

3 φ 3

0.1 φ 0

Clear hs

x hs Clear 1

Undocumented equrep

x φ' x φ x diff maple x hs x diff x hs equrep :

Use parenthesis with relational operators, just as best practice (which actually means "just in case").

Define again hs

x hs x 0.5 > (:

x φ x φ' 2 1 sys

What's the problem?: the correct result must implies δ Dirac

x φ' x 12 / > 1 x + (*

If you have a concentrated load at L = x you loose it
