Week 4 Project - Simple Crank Mechanism

Question 1:

In the case shown above, Revolute joints are located at P0 and P1, What type of joint must be given at P2 (Joint C) so that the system doesn't have redundancy issues?Answer: Inline joint created

NOTE: Joint C is a type of joint that will perform translational motion only along the X-axis (Basically Joint C is the slider of the crank-slider mechanism)

Also, prove why the joint you have selected will be the ideal joint for the system using DOF calculations, also, what type of joint is this?

Answer : Inline joint is created because it is having 2 DOF

Ideally, after you have selected the perfect joint for Joint C to reproduce the desired motion, what will be the final DOF of this system? also, validate with calculations

Answer : Final DOF for the complete system is 4.

Question2:

Now, plot a graph for velocity vs time on Joint C or Point P2 w.r.t the ground

Answer : done

Find the maximum velocity of Point P2 w.r.t the ground : done

What is the DOF of the system now and why?

Answer :3 DOF because we removed revolute joint at P1

Question4:

Now, again, plot a graph for the reaction torque vs time at P0 and explain your results

Asnswer :plotted

Question 3:

Now, plot a graph for the reaction torque vs time at P0 and explain your results

Answer: Plotted

Compare the range of motion of the crank mechanism between this case and the previous case and explain the reason for the difference if any

Answer: Plotted
