both major axis and minor axis bending as shown in Fig. 4. The ultimate load was normalised with yield strength of specimens‚ Py and eccentricity was normalised with x0‚ the distance of centroid of the angle cross section from shear centre. Fig. 4 shows that specimens subjected to minor axis bending failed at considerably lower load than those subjected to major axis bending. Rate of reduction of ultimate load is more pronounced in the case of minor axis bending. For example‚ the rate of reduction

heater core tubes includes three parts: the pressing machine‚ the bending machine‚ and the washing machine. The pressing machine takes seven seconds per tube; the bending machine takes 13 seconds per tube‚ and the washing machine takes 0.06 seconds per tube (60 seconds per 1000 tubes). Each of these processes runs simultaneously‚ so the theoretical capacity is constrained by the process that takes the longest period per tube: the bending machine. Under the current policy‚ Hilcrest Auto is operating two

Chapter 2 Basics of Vibration Dynamics Vibrations are mechanical oscillations about an equilibrium position. There are cases when vibrations are desirable‚ such as in certain types of machine tools or production lines. Most of the time‚ however‚ the vibration of mechanical systems is undesirable as it wastes energy‚ reduces efficiency and may be harmful or even dangerous. For example‚ passenger ride comfort in aircraft or automobiles is greatly affected by the vibrations caused by outside

SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment‚ a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion‚ S2O82-‚ was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability‚ coupled with its strong oxidizing ability allowed for stabilization of

Class 1 Metallic bonding: Found in metals and alloys‚ 1‚ 2‚ or 3 valence electrons that are not bound to any particular atom in the solid. They drift throughout the entire metal. This results in a sea of electrons. These free electrons result in good electrical and heat conductivity. Coordination number is 8 or 12 (number of nearest neighbors). Ionic Bonding Found in compounds that are composed of both metallic and nonmetallic elements. Metallic element gives up valence electrons to the

(2) inner bending‚ and (3) outer bending. The cutting process can produce at a rate of 150 pieces per minute; inner bending‚ 140 pieces per minute and outer bending‚ 110 pieces per minute a. Determine the hourly capacity of each process stage and the number of machines needed to meet an output rate of 20‚000 units per hour. 1. Cutting: 150(min) (60 min=9‚000/hour) = 20‚000/9‚000=2.22 machines needed 2. Inner Bending:140/min (60)= 8400/hour 20‚000/8400=2.38 machines needed 3. Outer Bending:110min(60)=6600/hour
