1. Consider 7. by 2-in, steel drill collars in a 124-invertical hole. If the WOB W = 2400) Ib Ind mud weight = 1.61 SG, determine: (1) Whether drill-collar buckling occurs and, if it does, the distance to the tangency point; (i) The inclination of the resultant force acting on the hit and the tili angle: Cub The side force at the bici (iv) The force that the buckled drill collar applies to the borehole wall: (1) The distance from the bit to the point of maximum bending stress and the corresponding bending 125 points) stress
