Hi there, I have a project of torsion bar. I need to know value of force is making a torque on it.(adsbygoogle = window.adsbygoogle || []).push({});

So I have a velocity [tex]V=40km/h[/tex], mass per wheel [tex]m=530kg[/tex], radius of wheel [tex]R=290 mm[/tex] and heigh of obstacle [tex]h = 6 cm[/tex]. What will be the reaction N, on both axis, of obstacle to tire? I have no idea how to calculate that.

Also, tire pressure is p = 0,2 MPa, tire stiffnes k = 150 000 N/m and tire supression is c= 150 Ns/m as tire will absorb some of impact force, but what value of force won;t be absorbed?
