2. Determine the diameter of suction cups required to lift a mass of 15kg if the suction is 60 kPa and three suction cups are used. Assume the acceleration due to gravity is 9.81 m/s^2. Use SI units throughout.3. a two-finger parallel air chuck is supplied with air at a pressure of 50psi. Assume that all of the force generated by the cylinder is transfered to the fingers of the grip. Also assume that the coefficient of friction between the grip and the object being picked up is 0.55. What is the maximum mass that can be picked up by the grip? Assume the acceleration due to gravity is 9.81 m/s^2. Use SI units throughout.
