Abstract: The typhoon makes a serious damage to the apple farmer by dropping apple before the harvest due to the strong wind. We investigated the drag coefficient C_D of apple models. We are focusing on the influence of the bag to cultivate the delicious fruit. The C_D was obtained in experimentally with or without bag. The drag force and the shear stress of stem under the condition of typhoon were determined from the obtained C_D. The drag force increased with using a bag, so that the shear force acting on model also increased. The obtained shear stress was compared with allowable shear stress of real tree. The direction of bag realizes the shear stress less than the allowable value. Thus, the dropping apple due to strong wind can decrease with the suitable shape of bag to decrease the drag force.
