problem 1-5, James M. Gere's mechanics of materials text book
for a, b and c he used the full 12k value of P to get the bearing and shear values. my logic was to analyse the forces when getting the shear on the pin G.
my instructure said we were using the max values of P, but that wasn't a satisfactory answer for me.
also : in a, the value for the bearing area is chosen to be 2dt where d is the diamter as shown. why isnt the bearing area as shown here? (hopefully that's a clear enough aiding diagram )
