A single-dwell cam will do the following profile: rise 5 inches for 90 degree, return 5 inches for 90 degree, dwell 180 degree. Generate the displacment, velocity, acceleration, and jerk curves three times using simple harmonic, cycloidal, and eighth order polynomials for both rise and return. Discuss which result is best given your analysis of the three sets of acceleration and jerk curves.

a. Consider a parabolic cam profile consisting of a rise-dwell-return-dwell cycle where the rise-cycle to full lift (L= 0.33 in) occurs over a 60° segment of shaft rotation. The shaft is turning at a constant speed of 100rpm. What is the velocity, acceleration and jerk of the follower at the mid-point of the rise-cycle? b. If the profile was now changed to a simple harmonic profile, what is the velocity, acceleration and jerk of the follower at the mid-point of...

Design a cam for a rise-return-dwell (RRD) application using the fourth order polynomial. The position, velocity, and acceleration should be zero at the beginning of the rise h, and the velocity should be zero at the end of the rise. Plot s, v, a, and j profiles for BOTH fourth and fifth order polynomials using EXCEL. (Note: this is to all be done by hand in regards to the fourth and fifth order polynomial. Only Excel can be used for...

Which of the following statements is true about a 360-degree appraisal? It involves using a single source for appraisal information. Usually, feedback is obtained only from top level managers. It often misses qualities that other appraisal methods capture. Often, the person being rated can select the appraisers. Its objective is to provide a basis for administrative decisions.
