The piston rod of a double-acting cylinder is to advance when a 3/2- way push button valve is actuated manually. The cylinder is to remain advanced until a second valve is actuated. The signal of the second valve can only take effect after the first valve has been released. The cylinder is to then return to the initial position. The cylinder is to remain in the initial position until a new start signal is given. The speed of the cylinder is to be adjustable in both directions.Draw the circuit diagram for the problem.
Assume that you are to design a 3V V-belt drive. Given that input speed as 1750 rpm and nominal output speed as 725 rpm. Starting with belt linear velocity 4000 ft/min, specify the output sheeve D2 once you specify D1 from last question.
D2 = ___ in.
Provide write down steps including equations.
*** 21.07 and 21.1 were marked incorrect
Complete the timing diagram and truth for the shift register.
