If the bearings got too hot, they would attain a noticeable odor, and an oilerwould give the bearing a squirt maquijas lubricant at the next train stop. Also, there is no shear stressdue to shear at the extreme location.

This philosophysuggests that systems be designed so that a failure can be detected before it occurs. Using a point on the circle of MPa, 30MPa ,the circle is drawn as follows: Mercury, being in molten form at roomtemperature, is not used in typical metal applications. Since strain gages are placed onsurfaces, this is possible, unless the machine element is being compressed, such as if it was in apressure vessel.

Using Castiglianostheorem, find the deflection at the free end in the z-direction. Find the stresses acting on a plane having the normal in the direction of thespace diagonal13,13, This problem requires evaluation of direction cosines from Equations B.

The diameter of the shaft is1. The first isfor xPage What is the ekementos in the string? The exact hole locations have not been specified, so some variation may occur withassumed dimensions. The safety can beincreased either by making the container wall thicker or by mounting a reserve tray underthe container to collect the maqhinas acid.

This problem uses Equations B. Choose the type of beam support and the position. The octahedral stresses are obtained from Equations 2. Find the loadclassification if P1s variation is sinuous and P2 is the load from a weighta If only P1 is applied. Some attentionmust be paid towards units. The cross sectional area of the string is: The wear rate per width is given by Equation 3.

This problem is similar to Problems 5.

A one gallon container has to be compact to be easily stored in a refrigerator. Determinewhether that is a good idea.

Also, find the critical section with the largest bendingmoment. Also, calculate the maximum bendingstress and the maximum beam deformation and their locations. Note that the other stresses are zero, so the principal stress out of theplane of the normal and shear stresses is zero. Assume that EI is constant. The obvious material choices are paper or plastic materials, although eementos and metal cans can be considered as possibilities.

The loading can be broken down into the first two cases in Table 5. The problem is statically indeterminate. The obvious solution is to make the wire of a polymer or other material with exactly the samedensity as water and with the same compressibility as water. The size of themoment equals the maximum moment, or Pl. Therefore, the maximum shear stress is, from Table 4. The horizontal portion could be covered with a high friction coating or tapeor glue to keep the trousers from sliding off. Comparing the critical load for the two failuremodes allows solution of the problem.

The tube material is AISI stainless steel. Draw the shear force and moment along thelength of the bar and give tabular results.

The fishing rod is 2m long. In this problem, theshear and moment diagrams are obtained through direct integration, as suggested by Equations 2. Therefore, from Equation 5.

The solution approach is the same as Problem 2. An alternativeapproach would be to evaluate the integrals in Maquihas 4.

Therefore, as the stiff material, usesilicon carbide, and as the compliant material, use natural rubber.

The elongation is obtained fromEquation 4. The stresses calculated are average stresses, and do not reflectthe distribution of shear stress in beams as covered in Chapter 4. Find the size of the cracks the glasstube can tolerate at 7.
