For problems that involve an object accelerating along an inclined plane, how can the weight be used to determine the force component that causes motion? The weight is the full force that acts perpendicular to the surface of the ramp.

The weight times the cosine of the ramp’s angle is the force perpendicular to the ramp.

The weight times the sine of the angle of the ramp acts down along the ramp.

The weight times the cosine of the angle of the ramp acts down along the ramp.
The answer is C ¨The weight times the sine of the angle of the ramp acts down along the ramp.¨

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?
