For the beam, why is the moment Mo negative? if i were to take the fixed point at A, Mo gives a smiling face which is the convention for positive. However, if i were to take the fixed point at B, Mo gives a sad face which is the convention of negative. So which fixed point should i take to determine the sign convention and why
