Control Systems, Pneumatic, Mechanical Engineering

I have small set of engineering questions need to be completed, they are related to mathematical and mechanical engineering. I have attached the requirements, let me know if you can complete the requirements attached. I need this work completed within a day or or two maximum, it should not take more than few hours to complete anyway. According to the requirements I am willing to pay around $25 for the project, and I will make the payment once I see some of the work completed. Thanks.
