First of all, if Figure 6.

Determine the shear force and bending moment in the bar, and find thecritical section with the largest bending moment. If the moment is positive, the slope is negative for positivex and positive for negative x.

The load intensity functioncan be written as: All stresses in sketch ff are in megapascals. Also, draw your results. Find whether the fiber strength of the fiber-matrix bond will determine thestrength of the composite. The Mohrs Circle approach described mquinas pages is used to solve this problem. Once the reactions are maquinws, the shear and moment diagrams can befound through the use of singularity functions.

The reactions have been sketched in red. This solution will ignore advanced concepts such as stress concentrations that would existat the fillet, since this material is covered later in the text.

The elemehtos factor guarding against crack propagation is obtained from the ratio of thefracture toughness of the material to the stress intensity factor calculated by Equation 6.


For a soda-lime glass of the same geometry only 7. Thestress intensity factor is therefore calculated from Equation 6. The viscosity ofthe lubricant is 0. Find the location x ofthe load and determine the stresses in each rod.

This problem does not hamrck determination of the stresses as in Problems 6.

The approach is similar to Problem 4. The approach is very similar to problem 2. Note that the radii of the circles areeasily calculated to give the principal shear stresses see Equation 2.

Note thatthe radii of the circles are easily calculated to give the principal shear stresses see Equation 2. Simultaneously, the shaft transmits a torque of Nm. Note that Kca and Kcbare functions of only d, since the other variables needed for their definition hamroock fixed.

Note that a ton is kgwhen the problem is stated in metric units. Find the torque transmitted through the shaft and theangular torsion of the 1-m-long shaft.

Therefore, ifA is the cost of the container with thicker walls, then the cost of the container with a reserve trayisA1. The fiber reinforced composite has the same elastic properties whether the reinforcement is glassor carbon fiber see Example 3.


The moment of inertia for the tube is: Determine thetriaxial stresses and give the corresponding Mohrs circle diagram. Therefore, the bendingstress is obtained from Equation 4.

The reactions have been drawn on the sketch in red. The yield strength of the shaft material isMPa. Also, the problem is simplified by using data from Table 4.

The two casesare given in Table 5. Once an expression is obtained for the moment of inertia,Equation 5.

A tera mm3 is mm3. Transverse shear can be neglected. While one can work in the x andy directions, the answer is more easily obtained by applying equilibrium to the coordinate systemwhich is defined by the section.

The three equations which will be used to solve the problem are maquimas equilibrium, momentequilibrium and a deflection requirement – that for the beam to remain horizontal, the deflectionhas to be the same at A and B. The problem is statically indeterminate. For the notched bar, from Figure 6. There are three sources of strain energy:
