A jet engine is attached to the wing of an airplane by a security screw (Figure A, marked in black) with a diameter of 40 mm whose purpose is to ensure that if, following a malfunction, the engine exerts too great a horizontal force F on the wing - the screw will break and the engine will detach from the wing, thus the wing will remain intact It is known that the weight of the engine is 3000 kg. A. When the engine exerts a force F of 10 kn, what types of stresses act on the screw? B. When the engine exerts a force F of 10 kn, what is the stress acting on the screw according to the Tarska criterion C. What types of deformations exist in the material when the engine applies a force F of [50] KN d. What is the maximum force F that the motor can apply to a screw without the screw breaking
