Gear in Draw-works. Draw-works is the machine on the rig consisting of a large-diameter steel spool‚ brakes‚ a power source and assorted auxiliary devices. The primary function of the draw works is to reel out and reel in the drilling line‚ a large diameter wire rope‚ in a controlled fashion. The drilling line is reeled over the crown block and traveling block to gain mechanical advantage in a "block and tackle" or "pulley" fashion. This reeling out and in of the drilling line causes the traveling

Storing Data In DBMS (Traditional Models) Introduction A computer database relies upon software to organize the storage of data. This software is known as a database management system (DBMS). Database management systems are categorized according to the database model that they support. The model tends to determine the query languages that are available to access the database. A great deal of the internal engineering of a DBMS‚ however‚ is independent of the data model

MECH 8250 – Building Systems Module 1 - Heating Load Calculations Module 1 Heating Load Calculations The amount of heat is required for the building heating system to maintain a balance of the building heat loss. The amount of heat and moisture are gained from the building internal and external heat sources that is required to be removed by the building cooling system. Both heating and cooling loads form the basis in designing the HVAC systems for the building and occupied spaces to achieve both

Acid-Base Calculations The Ion-Product Constant for Water‚ Kw Water undergoes ionization to a small extent: H20(l) H+(aq) + OH–(aq) The equilibrium constant for the reaction is the ion-product constant for water Kw: (1) This is a key equation in acid-base chemistry. Note that the product of [H+] and [OH–] is a constant at a given temperature (Eq(1) value is for 25oC). Thus as the hydrogen ion concentration of a solution increases‚ the hydroxide ion concentration decreases

suggest about women status in this play? What other evidence can you find to support your view? Measure for Measure is a play written by William Shakespeare in the seventeenth century which crucially presents the role of women. Women were viewed as pure and were not expected to be promiscuous‚ but dependent on men with few options or choices. Shakespeare’s interpretation of women in Measure for Measure very much reflects society’s opinion of women at the time‚ where men had more freedom and should
