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.
each of the two systems is released from rest. calculate the velocity v of each 25 kg cylinder after the 20 kg cylinder
water vapor at 3.0 mpa and 300c state 1 is cooled to 200cstate 2 then is isothermically compressed to 2.5mpa state 31.
a gas turbine power plant operates under the brayton cycle which is non-ideal due to heat losses from the compressor
A closed gas turbine unit uses neon as the working fluid. There are two stages of compression with inter cooling from 480kPa and 290K to a maximum pressure of 2.75MPa with an intermediate pressure of 1149kPa. The regenerator has an effectiveness of 6..

you have been asked to design an experiment to measure aerodynamic forces on a building using a 180 scale replica of
Determine (a) the final temperature of the gas and (b) the final pressure if no mass was withdrawn from the tank and the same final temperature was reached at the end of the process.
Saturated liquid water at 30°C and 1.8 m/s enters a long brass (k = 108 W/m-K) condenser tube with inner diameter of 1.45 cm and outer diameter of 1.6 cm. The heat transfer coefficient for condensation at the outer surface of the tube is 12,232 W/m2-..
