Emergency homework. I’m mechanical engineering student and I cannot my homework please help…

MFGE 316 – MACHINE ELEMENTSHomework 4- Fatigue Failure CriteriaDue:Question 1) The flat steel spring illustrated is loaded in bending by the force F. Thespring supports a static weight of exactly 9.36 kN. During operation, the total load onthe spring is estimated to fluctuate up to 10.67 kN maximum. The spring is forged of a95-point carbon steel and after heat treatment has the following minimum properties:Sut = 1400 Mpa; Syt = 950 Mpa; HB = 399, and 32 percent reduction in area. Estimatethe factor of safety if the spring is 18 mm thick, by using Goodman Equation. Question 2) The below figure is for a rotating shaft loaded in completely reversedbending by the the 500 N and 2000 N forces. Rotating speed of the shaft is 980 rpmand the shaft is made of 30CrNiMo8 (EN 10083) in quenched and tempered conditionwith a ground finish in critical places. The shaft has 2 mm shoulder fillets.a) Draw shear force and bending moment diagrams and calculate the stress atthe most critical point.b) Based on an infinite life, find the factor of safety by using Goodman Equation.c) If shaft has not an infinite life, calculate life for the shaft.d) If material for the shaft is C35 (EN 10083) in normalized condition, what willbe factor of safety in terms of infinite life (Goodman Equation) and life forthe shaft?
