The grain of a wooden member forms an angle 15° with the vertical. for τxy = 253 psi, determine the in-plane shearing stress parallel to the grain and the normal stress perpendicular to the grain. (round the final answers to one decimal place.)

This energy transformation diagram represents the energy of a skateboarder moving along a half-pipe. as she skates toward the top of the half-pipe, her original kinetic energy is converted to potential energy and friction. how much of the energy is potential?
