The factor of safety for a machine element depends on the particular point selected for the analysis.
This bar is made of AISI 1006 cold-drawn steel (Sy=280MPa) and it is loaded by the forces F=0.55kN, P=8.0kN and T=30N.m. Based upon the Von Misses theory, determine the safety factor for points A and B.

Answers

Based upon the Von Mises theory, the safety factor for points A and B are 2.77 and 6.22 respectively.

How to calculate the safety factor for points A and B?

From the diagram of this bar made of AISI 1006 cold-drawn steel shown in the image attached below, we can logically deduce the following parameters:

Stress, Sy = 280 MPa.Force, F = 0.55 kN to N = 550 N.Pressure, P = 8.0 kN to N = 800 N.Surface tension, T = 30 Nm.Length, l = 100 mm to m = 0.1 m.Diameter, d = 200 mm to m = 0.02 m.

At point A, the stress is given by this equation:

σx = Mc/I + P/Area

[tex]\sigma_x = \frac{Fl(\frac{d}{2}) }{\frac{\pi d^2}{64} } +\frac{P}{\frac{\pi d^2}{4} } \\\\[/tex]

σx = 32Fl/πd³ + 4P/πd²

Substituting the given parameters into the formula, we have;

σx = 32(550)(0.1)/π(0.02)³ + 4(800)/π(0.02)²

σx = 95.49 MPa.

Next, we would determine the torque:

Mathematically, torque can be calculated by using this formula:

τxy = Tr/J = 16T/πd³

τxy = 16(30)/π(0.02)³

τxy = 19.10 MPa.

From Von Misses theory, we have:

σVM = √(σx² + 3τxy²)

σVM = √(95.49² + 3(19.10)²)

σVM = 101.1 MPa.

Now, we can calculate the safety factor for point A:

n = Sy/σVM

n = 280/101.1

n = 2.77.

At point B, the stress is given by this equation:

σx = 4P/πd²

σx = 4(800)/π(0.02)²

σx = 25.47 MPa.

Next, we would determine the torque:

Mathematically, torque can be calculated by using this formula:

τxy = Tr/J = 16T/πd³ + 4V/3A

τxy = 16(30)/π(0.02)³ + 4(550)/3π(0.02)³

τxy = 21.43 MPa.

From Von Mises theory, we have:

σVM = √(σx² + 3τxy²)

σVM = √(25.47² + 3(21.43)²)

σVM = 45.02 MPa.

Now, we can calculate the safety factor for point B:

n = Sy/σVM

n = 280/45.02

n = 6.22.
