income and balance sheet for 1996 assuming the bank grants Dunham a $675K note payable at 12 percent and no existing interest-bearing debt is retired. Dividends will be 50 percent of net income. Cash will be the balancing item. Calculate the firm’s 1996 minimum cash balance by assuming that the average cash balance between 1993 to 1995 is the required 1996 cash balance. Use any extra cash at the end of 1996 to retire notes payable and redo the pro forma statements for 1996. Calculate Dunham’s financial

WHAT IS METAL? A metal is a chemical element that is a good conductor of both electricity and heat. Metals are malleable and ductile and have lustrous appearance. They have moderate to high physical constants and high tensile strength. Metals are further divided into two main groups - ferrous and non ferrous metals. TYPES OF METAL • FERROUS METAL These are metals which contain iron. They may have small amounts of other metals or other elements added‚ to give the required properties

Part A. Injection molding of polypropylene samples for mechanical testing. Introduction Injection molding is the most productive and popular polymer processing techniques. Almost 70% of all plastic parts are made using injection molding. Injection molding of plastics is a process similar to die casting of metals. Molten polymer is injected under pressure into a mold. Method Put the plastic material (Polypropylene) in granular form into the hopper. Set the injection molding temperature:
