A plant produces 300 units of an equipment a month of P3,600 each. A unit sells for P4,800.00. The company has 10,000 shares of stock at P200 par value whose annual dividend is 20%. The fixed cost of production is P120,000 a month. (a) What is the break-even point? (b) What is the"unhealthy point"? (c) What is the profit or loss if production is 60% Of capacity? Ans.(a) 100 units/month, (b) 128 units/month, (c) P62,667 per month
Design Against Fluctuating Loads
Machine elements are subjected to varieties of loads, some components are subjected to static loads, while some machine components are subjected to fluctuating loads, whose load magnitude tends to fluctuate. The components of a machine, when rotating at a high speed, are subjected to a high degree of load, which fluctuates from a high value to a low value. For the machine elements under the action of static loads, static failure theories are applied to know the safe and hazardous working conditions and regions. However, most of the machine elements are subjected to variable or fluctuating stresses, due to the nature of load that fluctuates from high magnitude to low magnitude. Also, the nature of the loads is repetitive. For instance, shafts, bearings, cams and followers, and so on.
Design Against Fluctuating Load
Stress is defined as force per unit area. When there is localization of huge stresses in mechanical components, due to irregularities present in components and sudden changes in cross-section is known as stress concentration. For example, groves, keyways, screw threads, oil holes, splines etc. are irregularities.
