Effects of Loading on Block

In this simulation, you can input normal, perpendicular, and/or shear forces to a block of mild steel.
Positive forces act in the directions shown in the figure (ie, tension is positive).
The original, unloaded block is a darker gray with solid yellow lines.
The loaded block is a lighter gray with dashed yellow lines.

Input Axial/Longitudinal Force Fx (in N)
Input Perpendicular Force Fy (in N)
Input Shear Force Fxy (in N)

Material Properties used in Simulation: E = 250 GPa; G = 80 MPa; v = 0.29
Block has length 300 mm, height 100 mm, and depth 100 mm (rectangular cross-sectional area)
Challenges:
1. Write down the equations for displacements in x and y due to forces Fx, Fy, and Fxy.
2. Determine which value of Fx makes the loaded block stretch to the end of the Fx arrow.
3. Calculate the corresponding displacement in y due to the Fx for Q2.
4. Identify a combinations of loads that make the loaded block cover the entire "Fxy" in the picture.
5. Consider what would happen if the up arrow near Fxy was instead a down arrow (you can't do this in the simulation).
