Arigid object is rotating in a counterclockwise sense around a fixed axis. each of the following pairs of quantities represents an initial angular position and a final angular position of the rigid object.
(a) which of the sets can only occur if the rigid object rotates through more than 180°?

1) 3 rad, 6 rad
2) -1 rad, 1 rad
3) 1 rad, 5 rad

(b) suppose the change in angular position for each of these pairs of values occurs in 1 s. which value represents the lowest average angular speed?
1) -1 rad, 1 rad
2) 3 rad, 6 rad
3) 1 rad, 5 rad

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz. what wavelength is produced?

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?
