Abstract An idealized model is proposed for heating of a pneumatic tire. A solution is obtained for the temperature rise of such a model. Using known thermal properties of rubber and known heat transfer coefficients, the time to reach thermal equilibrium is estimated.

Distribution Of Stresses

Abstract The semicircular plate subjected to bending usually is considered as a particular case of a sectorial plate and one introduces polar co-ordinates to discuss the deflection of the plate and the corresponding distribution of stresses. If the semicircular plate is clamped along the boundary the application of approximate methods becomes necessary to this end. It is worthy of note that a rather simple exact solution can be given in this latter case by making use of bipolar instead of polar co-ordinates.

General Method

Abstract An approximate solution for the distribution of stresses in a rotating prismatic shaft, of triangular cross section, is presented in this paper. A general method is employed which may be applied in obtaining approximate solutions for the stress distribution for rotating prismatic shapes, for the cases of either generalized plane stress or plane strain. Polynomials are used which exactly satisfy the biharmonic equation and the symmetry conditions, and which approximately satisfy the boundary conditions.

Distribution Of Stresses

The paper presents the results of a study on the distribution of stresses on the contours of underground workings, the cross section of which has the form of a trapezoid and an ellipse. The distribution of stresses at the points of workings contours is obtained at the given values of uniform pressure and the lateral expansion coefficient of the rock. The graphic images of stress diagrams acting on the contours of the considered workings are given.

400 m long and 16 m wide Simpang Dewa Ruci underpass construction project is a new one in Bali. It is of drilled pile system which need heavy equipment for drilling.The purpose of this study is to find out the unit price of some heavy equipment, like drill pile, excavator back hoe, dump truck, wheel dozer, tandem vibratory roller, asphalt finisher, and pneumatic tire roller.The calculations result in unit price of job the drill with drill pile at IDR 93,921.79/m3, unit price of job entrenchment and soil moving with excavator back hoe at IDR 14,656.22/m3, unit price earth moving work with dump truck at IDR 38,324.82/m3, unit price leveling congeries with whell dozer at IDR 2,644.87/m3, unit price soil compaction and asphalt compaction with tandem vibratory roller at IDR 4,034.93/m3, unit price of the spreading asphalt with asphalt finisher at IDR 34,637.50/m3, and unit price asphalt compaction with pneumatic tire roller at IDR 13,478.42/m3.Keywords: capacity, heavy equipment, productivity, unit price, use
