An arrow is shown, where the most critical part (r) of said arrow is observed.to. It is designed with approximate relative sizes of d = 0.65D and r = D/15 with the diameter d conforming to the size of the inner diameters of standard metric bearings.b. It is made of SAE 2340 steel, heat treated to obtain minimum strengths in the shoulder area of Sut = 1226 MPa and Sy = 1130 MPa.c. At the shoulder, the arrow is subjected to a completely reversible bending moment of M = 80N and a uniform torque of T = 55Nmd. It has a safety factor n = 2
Determine the dimensions of the shaft for infinite life.
A bracket is under a loading condition shown below. It's made from a steel with yield strength (Sy) of 42 ksi and ultimate tensile strength (Sut) of 76 ksi. The diameter is 0.42 in and b = 1.75 in, with the load P fluctuate between 15 lbs (tension) and -5 lbs (compression).
Using the modified Goodman or Gerber criterion, determine the fatigue factor of safety based on infinite life. If infinite life is not predicted, estimate the number of cycles to failure. Also check for yielding.
A helical compression spring is made of a specialty alloy wire with a wire diameter d = 4 mm and an inner coil diameter Di = 18 mm. For this type of alloy and specified wire diameter, the shear yield strength is 715 MPa and the modulus of rigidity is 77.2 GPa. If the spring has 9 active coils, determine the factor of safety nd when the spring deflection is 7 mm.
