2) (120 pts) After successfully landing on the planet Mars, some scientists want to experimentally test the compressor mechanism given below. The compressor mechanism shown below is driven clockwise by a DC electric motor at a constant rate of 800 rpm, and accelerating at 1000 rad/s'. In the position shown, the cylinder pressure is 70 psi, and the plston weighs 2 lb. The coefficient of friction between the piston and the compressor cylinder is 0.5. The weight of all other links is negligible. Find the followings for this mechanism (you.can use analtical or Note: The gravity of Mars 3.71m/s: NOTE: For graphical solutions, please submit include images from your CAD file showing your answers, and drawings of the mechanism, relative velocity vector and relative acceleration vector diagrams with important dimensions and angles included on them. You must also label all joints, links, velocities, and accelerations on your drawings clearly.If you are using a CAD software for your solution, you must also upload your CAD file in addition to the Word/PDF file. If you are using an gnalrtical method, you must exclusively include all your solution methods and equations to show how you find each data. Skipping solution methods might result in losing some points. Even for the graphical solution, you must still show how you find the important data by showing your calculations for each section. Not doing so may also result in losing some points a MS Word or PDF file which will 7- 1.5 65 70 psi 1 .75、 (a) Draw kinematic diagram of this mechanism, and label all the links and joints (10 pts) (b) Find its total number of links, joints, then its degree of freedom (10 points) (c) Find the velocity of piston using the relative velocity method, and drawing the relative velocity diagram including all the angles that each velocity components make with the parallel (x) axis (10 points) (d) Find the acceleration of piston using the relative acceleration method, and drawing the relative acceleration diagram including all the angles that each acceleration components make with the parallel (x) axis (20 points) (e) Calculate the force that the gas cause on the piston (10 points) (f Calculate the friction force between the piston and the compressor cylinder (10 points (g) Calculate the forces at each joint using static/dynamic equilibrium, and including all the FBDs (20 points) (h) Calculate the reaction forces where the crank is connected to the base/motor (10 points) 0) Determine the torque required from motor to operate the compressor (20 points)
