A support beam used in one of the designs for the theme park, is subjected to vibrations along its length; emanating from two machines situated at opposite ends of the beam. The displacement caused by the vibrations can be modelled by the attached equations:
For the attached equations you are required to determine the followings for the vibration of this beam:
1-At what time does each vibration first reach a displacement of −2mm?
2- Use the compound angle formulae to expand x1 and x2 into the form
A sin 100πt +-B cos 100πt, where A and B are numbers to be found.
3-Using your answers from part 2, express in a similar form. Convert this expression into the equivalent form R sin (100πt + α)
Step by step
Solved in 5 steps
Can you please answer the attached question, and convert it to the form ? sin (100?? +α)
has this answered question 3?
- Express in a manner similar to just what they did in part (2) with their responses. R sin (100πt+α) is the equivalent form of this expression.
