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.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
