Design and analyze cam profiles. Using MATLAB code, 1. Draw the displacement and velocity diagrams for the complete motion cycle, clearly demarcating the different regions of motion
2. Draw the pitch curve showing the Base circle as well.
3. Keep the base circle radius fixed and change the ‘lift’ value by 30% in the increments of 10%. Study the effect of this on the pitch curve compared to the original curve got in (2) above.
Speed of the cam can be assumed if necessary.
Note:
Follower type: Knife edge
Event sequence: Dwell-Rise-Dwell-Fall
Event: Rise from 120 to 210 and Fall from 270 to 360
Motion type: Parabolic
Rb(mm):65, Rf(mm):16, Lift(mm):39

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.
