A plank 2.00 cm thick and 14.0 cm wide is tightly attached to the railing of a ship by clamps so that the rest of the board extends 2.00 m horizontally over the sea below. A man of mass 70.5 kg is forced to stand on the very end. If the end of the board drops with 5.70 cm because of the man's weight, discover the shear modulus of the wood.
