Guys, why do you think the standard nail is designed with a pointed end and where the top has a cap? What does this imply to the 2 kinds of stress which are normal stress and shear stress? Isn't the pointed end kinda works like a wedge?
Also, why does a homogenous material when broken is always cut at an angle of almost 45 degrees?
