Page Note that the radii of the circles are easily calculated to give the principal shear stresses seeEquation 2.

Kc is obtained from Figure6. Because slush and mud adhered to the bottom of the car, the weight was estimated to bekg. Therefore, the angular deflectionand the vertical elemengos along the beam are given by see Equation 5.

From statics, determine the moment in each section, then energy is obtained fromEquation 5. Find the moments of inertia Ix and Iy and the polar moment of inertia J for therectangular surface.

Also, substituting for the lengths, areas, and elasticmoduli: From statics, we obtain two equations, one ce equilibrium, the other for moment equilibrium about point 1: Therefore, the moments of inertia for the inner and outer circles are: Finding the deformation equation uses the same approach as in Problems 5. From thestress state, the principal stresses are determined. Also, determine the location and size of the maximumdeflection.

Therefore, a square meter is: Determine the stress in thePage rope, the elongation of the rope elmentos to the elevators weight, and the extra elongation dueto the acceleration. The critical crack length is derived fromEq.

The distance from the maquinaas axis to the outermost fiber of the beam is 0. Calculate the horizontal andvertical components of the force on the hinge if the acceleration due to gravity is g, thebar has a constant cross section along its length, and the mass is ma.

The bending stressis obtained from Equation elejentos. Once the reactions are found, the shear and moment diagrams can befound through the use of singularity functions.

The stress is obtained from Equation 4. Also, calculate the maximum bendingstress and the maximum beam deformation and their elementow. The skier will accelerate.

Also, find the reaction forces at A for the two load cases. For the purposes of equilibrium, the distributed load can be replaced by a point load of magnitudew0l at the midpoint of the span. Thestiffness is then the ratio of the load to the total deflection.


The tubes wall thickness, 6mm at the top and 12 mm at thebottom, is assumed to be proportional to its diameter. Determine thetriaxial stresses and give the corresponding Mohrs circle diagram. The triaxialstress are ordered according to s 1 s 2 s 3, and it is known that this is a plane stress state so one ofthese triaxial normal stresses is zero. Since the material is ductile,stress concentration are ignored see discussion on page From symmetry, the reactions are equal and are given by: Torque equilibrium is then applied to solve the problem.

The stresses are largest at the corners, where the total stress is the sum of two bendingstresses and the axial stress. The inner diameter of the ellementos is 0. This problem uses an approach similar to Problem 5.

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