SLL 07: Beam on elastic foundation, simply supported ends

Description

Material		Modulus of elasticity	$E=210 000 N/mm^2$
Geometry	Cross-section	Moment of inertia	$I=100 000 000 mm^4$
	Boundary conditions	In points A & C	$R_y$ fixed
		Subgrade	$k=840 kN/m/m$
Loads		In points A & C	$M=15 kNm$
		In point B	$F=10 kN$
		On the entire beam	$p=5 kN/m$
Mesh		Number of divisions	20
