Hi everyone,
I'm struggling to get my head around the convention of internal moments and shear forces of a loaded beam.
I just can't seem to make any sense of why F is facing upwards and F+dF is facing downwards. It's driving me absolutely insane. Surely both of them will be facing upwards to cancel out wdx?
Please help =/
Thank you.
