Write down the first three steps of the scientific method as they are presented in the assigned reading. use a topic of interest to you -- for example, ethnic diversity in college, homecoming rituals, athletic scholarships, or teens eating tide pods; take that topic through the first steps of the process. for each step, write a few sentences or a paragraph: 1) ask a question about the topic. 2) do some research and write down the titles of some articles or books you’d want to read about the topic. 3) formulate a hypothesis.

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.

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
