Statically inteterminate reaction force analysis VM001

An assembly of three cylinder bars is supported at both end surfaces. Forces $F_1$ and $F_2$ is applied on the middle of the assembly as shown in Figure [fig:ch5_vm_001_schematic].

The input data about material, geometry, and loads are given in Table [tab:ch5_vm_001_parameters].

Material Properties	Geometric Properties	Boundary Conditions
Young's Modulus E=2e11	h=10	$F_1$=2000
Mass Density $\rho$=7850	a=3	$F_2$=1000
Poission's Ratio v=0.3	b=3

The geometries and imposed boundary conditions are shown in Figure [fig:ch5_vm_001_bc].

The result comparison is given in Table [tab:ch5_vm_001_result].

Results	Theory	WELSIM	Error (%)
Z Reaction Force at Top Fixed Support	1800	1810	0.556
Z Reaction Force at Bottom Fixed Support	1200	1202	0.167
