Determine the resultant internal normal and shear force in the member at (a) section a-a and (b) section b-b, each of which passes through the centroid A. The 500-Ib load is applied along the centroidal axis of the member.

The duration of a photographic flash is related to an rc time constantly

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
