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 make sure 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 and thus the wing will remain intact (Figure B). It is known that the weight of the engine is 3000 kg. A. When the engine exerts a force F of size 10[kn] what types of stress act on the screw? B. When the engine exerts a force F of size 10[kn] what is the stress acting on the screw according to TRESCA criterion C. What types of strains are present in the material when the engine exerts a force F of [50] KN d. What is the maximum force F that the engine can apply to a screw without the screw breaking These are the properties of the material the screw is made of:
