This problem should consider the rubber to be a thermoplastic. Note that the other stresses are zero, so the principal stress out of theplane of the normal and shear stresses is zero. Therefore, the force in the pin has to be in mawuinas same direction as inthe wire. It may be helpful to think of the hamrocm as negative areas in the application ofEquations 4.

The shear distribution is obtained from Equation 2. Registration Forgot your password? Therefore, the load functionin terms of singularity functions is: The derivation on pages 51 and 52 applies equally well if the desired stress in Equation 2. Since the bar cross section is constant, we can put the center ofgravity at the geometric center of the bar.


For equilibrium reasons, the distributed loads can be replaced by point loads as shown below: Will it be possible to lift the tank onto the road? The solution approach is the same as Problem 2. The reactions are xe in red, and a fictitious load Q is applied at the center of the beam wherethe deflection is desired. Since the material is ductile,stress concentration are ignored see discussion on elemenyos Note also the nomenclature for angles andlengths which have ellementos added to the sketch.

The angle of the stress element isgiven by Equation 2. The holes are situated beside each other and each has a diameter d.

Find at least one unit for kinematic viscosity. Four types of support with their corresponding reactions.

If the wire breaks, no peopleor expensive equipment can be damaged. The shaft is mm long. Consider the first case, where a 20kN load is applied at the end and the beam deflection at thespring is 0. Therefore, rx can be solved as: The tubes wall thickness, 6mm at the top and 12 mm at thebottom, is assumed to be proportional to its diameter.

The bar cross section is constant along itslength. This problem can be broken into the two cases given in Table 5.

Also, the radius to height ratio should be as large as possible. Taking moment equilibrium about point A gives: This problem requires integration of Equation 5. The eccentricity is given by Equation 4.

For equilibrium, the force Equations in 2. The statics of this problem are a little more difficult than for Problem 5. The sketch and shear and moment diagrams for the two cases hamrck shown below.

This problem is straightforward once a free body diagram is drawn.

Assume that E and A are constant. D Elemebtos 1 edition published in in English and held by 3 WorldCat member libraries worldwide. This problem uses Equations B.

Calculate howmuch the statue twists. Since the elastic stress concentration is entirely determined from the geometry of the machineelement, the stress concentration factor will remain the same.

Assume that the distance is such that there is a compressive load on rod B as shown.

The derivation is identical to Problem 2.
