compressional stress & shear stress

[petep]

A force of 500 N is applied at an angle of 37 degrees to the surface of the end of a square bar. that surface is 4.0 cm on a side. what are the compressional & shear stress on the bar? material processing class and i don't know the eqation or where to start someone help please

You need to specify more information on this problem. What are the boundary (fixed point) conditions, i.e. is it a cantilever beam (one end fixed, one end free)? I assume that is the geometry for this problem.

Also I presume the horizontal component of the force vector is pointing toward the fixed end, in order to put the entire beam in compression.

So assuming it this is a cantilevered beam, what are the equations for a cantilever beam in deflection? Think of the horizontal and vertical components. You may ignore torsion.

Are you familiar with superposition?
