PROBLEM 7.82 - 100 MPa Solve Prob. 7.81, using the maximum-shearing-stress criterion. PROBLEM 7.81 The state of plane stress shown occurs in a machine component made of a steel with oy = 325 MPa. Using the maximum-distortion-energy criterion, determine whether yield will occur when (a) o = 200 MPa, (b) o = 240 MPa, (C) 00 = 280 MPa. If yield does not occur, determine the corresponding factor of safety.

Two contacting rollers used for a machine application. They run together with a combination of rolling and 9% sliding. The resulting maximum compressive principal stress in the contact zone is 16500 psi. Both rollers are made from 6061-T6 hard anodized aluminum. The design life of the rollers is 3.5 years of 2-shift operation at 260 days/year and they each turn at 220 rpm. What is the expected safety factor against pitting for the roller pair?

Problems 1. (Subtotal: 21 points) A steady torque of 1500 Ibf in is transmitted by a machined shaft made of steel with an ultimate tensile strength of 100 kpsi. The transverse cross section at the location of a shoulder against which a gear sits is subjected to a bending moment which is a sinusoidal function of time with a maximum of 800 lbf-in. Furthermore, this cross section is the location for the maximum von Mises stress. The smaller diameter at...

Q3. A rectangular cross sectioned cantilever beam is 300 mm long and has a half bridge gauge at a distance 200.0 from the free end, whose width is twice the height. If the load applied at the free end is 15 kg, the V, is measured to be 150 micro volts. The gauge factor is given as 2.14 and the applied voltage V, is given a 5V and hence the equation for half bridge is given as E a) Determine...
