Question 1: Submit the m-file on Blackboard under Project P2 Q1 Actuators 2 and 3 are locked retacted by 5 in from fully extented position respectively. Actuator one is being retrated at a constant velocity of 2 in/s.
1. Calculate the position of poid D when Piston 1 is retracted 8 in from fully extented position.
2. Calculate the force developed by the actuator when Piston 1 is retracted 8 in from fully extented position. (Your program should only display the position of point D and the force F dveloped by the piston in the coordinate system of origine O)
Question 2: Submit the m-file on Blackboard Project P2 Q2 Actuators 2 and 3 are locked retacted by 5 in from fully extented position respectively. Actuator 1 is being retrated at a constant velocity of 2 in/s.
1. Plot the position of poid D as a function of the piston axial position when it is being retracted from from fully extented position by 8 in.
2. Plot the force developed by the actuator as a function of the piston axial position when it is being retracted from from fully extented position by 8 in. (Your program should plot two figures: One for the position of point D and one for the force F)
