Question 1
1.1 The mechanical system and the control system. The mechanical system is a set
of physical components that convert an input motion into a desired output
motion for example a car lift. A control system manages or regulates the behavior
of other devices or systems using control loops. It can range from single home
heating controller using a thermostat controlling a domestic boiler to large
industrial control systems for example a software.
1.2
Mechanical system Control system
Uses of hydraulic presses It uses an electronic
Plain hydraulic presses and hand-level It uses a pneumatic
hydraulic presses
1.3) Mechanical system because it is used to lift up heavy objects and allow
mechanical workers to work underneath the car without laying on the floor.
1.4) Cylinder transmit hydraulic pressure to the slave cylinder when the pedal is
pressed, and if the pressure is applied on one cylinder. The other one will move to
lift the objects and the pump to transport the fluid, which is in the form of oil to
the cylinders. The value mounted in the cylinders should be closed when oil is
pumped from the chamber to boost the pressure inside the cylinder.
1.5) it is important to have air because without air objects will not be easy to be
lifted. The cylinder should be closed when oil is pumped into the chamber to
increase the pressure.
Use the tools and machines properly
Wear protective gear
Always ensure the tools are clean
Use the proper tool for the job
Do not run or rush in the workshop
Do not use a machine if you have not been shown how to operate it safely
Be patient when you use machines
Do not use worn out tools
