I need the real handdrawing complete it by adding these :
Pneumatic Valves
Each linear actuator must be controlled by a directional control valve (DCV) (e.g., 5/2 or 4/2 valve).
The bi-directional motor requires a reversible valve to change rotation direction.
Pressure Regulators & Air Supply
Include two pressure regulators as per the assignment requirement.
Show the main compressed air supply line connecting all components.
Limit Switches & Safety Features
Attach limit switches to each actuator to detect positions.
Implement a two-handed push-button safety system to control actuator movement.
Connections Between Components
Draw air supply lines linking the compressor, valves, and actuators.
Clearly label all inputs and outputs for better understanding.

This clamp has the dimensions given in the table below the figure, and its jaws are mm thick (in the direction perpendicular to the plane of the picture). a.) The screws of the clamp are adjusted so that there is a uniform pressure of P = 150 kPa being applied to the workpieces by the jaws. Determine the force carried in each screw. Hint: the uniform pressure can be modeled in 2-D as a uniform distributed load with intensity w = Pt (units of N/m) acting over the length of contact between the jaw and the workpiece. b.) Determine the minimum vertical force (parallel to the jaws) required to pull either one of the workpieces out of the clamp jaws.
