Write the theoretical demand equation using the appropriate variable names you created when you prepared data for analysis. The variable names should be very short and must be in capital letters. For instance, QTY for Y, PRPIZZA for X1, PRSDRK for X2. Note that if you used QTY for quantity, use QTY in the estimating demand equation rather than Y. Remember to use the exact same variable names you used in the data. In other word, do NOT use Y and X1, X2, X3, and so on, as done in the textbook. I am trying to teach you a proper way of teaching you how to prepare a technical paper.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
