Problem 1- For the cam-follower system, the slotted bar has a constant angular velocity of 10 rad/s, and the follower A's radial position is given by:
r = 1 + 0.5 cos(2θ) ft
Determine the magnitudes of the follower's velocity and acceleration when θ = 30°.
Problem 2-The student starts from rest at the caller and runs away with a constant radial acceleration 0.5 m/s2 (with respect to the platform) as shown. The platform rotates at constant angular velocity 0.2 rad/s. Determine the magnitudes of the student's velocity and acceleration alter 3 seconds.
Steam enters a nozzle at 4 MPa and 640°C with a velocity of 20 m/s. This process may be considered reversible and adiabatic. The nozzle exit pressure is 0.1 MPa. (a) Draw a sketch of this process. Include all known information. (b) What is the entro..
