ME 371 cam Homework 7 Due in class on NOV.10,2014 CID: Name: Please use A4 size paper and staple them together. Probleml: Find the pressure angle at the point D of following cam mechanisms 0 D Problem 2: In Fig.P6.5,the displacement-time,velocity-time,and acceleration-time curves are sketched for a follower.The cam rotates at a constant angular velocity wand the maximum(peak)value of the acceleration is 5 units.The equation for the acceleration-time curve is as follows: A- B2 sin (a)Write the equations for the velocity-time and displacement-time curves. (b)Determine the maximum values of displacement and velocity
