Mechanical Engineering

Mechanical and structural members are designed to resist loads or forces. Generally, there is a mathematical relationship between the applied loads and some quantity such as stress, strain, deflection, strain energy, etc. Also, each material has a unique relationship between stress and strain. Experimentally, the relationship between loads and strains can be obtained directly by measurement utilizing strain gauges. Material behavior, or solid mechanics involving stress or failure due to overload is a typical assignment.

Position, velocity, acceleration and time are related mathematically, and are used to describe motion. Forces and accelerations are related. Depending on the situations, one can find either the force or motion with the other given as known information. Fundamental force laws and energy principles are used to analyze problems; such as trajectories, impact, mechanisms, machines, vehicles and mechanical vibrations. In the analysis of collisions, whether machinery mechanisms, cars, bikes or hockey pucks are all mathematically identified. These problems are typical of Meridan One assignments.

Pressure can exist due to hydraulic and pneumatic conditions, and can be used to transmit energy, amplify forces and control processes. Pressure is often contained and manipulated in piping systems and vessels by valves, regulators and other mechanical fixtures. Problems associated with performance; such as leakage, water-hammer effects, piping support systems, freezing and pipe and fixture failure should be evaluated for critical installations. Direct experience in piping systems is typical of Meridan One's work product.

Combustion processes are used to create mechanical energy and heat materials, and produce chemical and physical changes. Combustion processes power our vehicles, warm our environments and process our foods. The compression ratio, fuel/air ratio and heat transfer coefficients can significantly change the performance of these machines and processes. Whether watercraft jets or lawn and garden equipment, both involve engines as their source of power, and typical of Meridian One assignments.

Power transmission systems move energy of motion from one location to another to perform a function. Links, slides, gears, chains, cams and pulleys are examples of mechanical components that transmit mechanical motion. In vehicles, transmissions change speeds and torques to allow for smooth and efficient propulsion. Whether designing machines or assessing the safety of the machine, Meridian One is fully capable of the assignment.

Point-of-operation locations are positions where mechanical work is being performed. On a mechanical power press, for example, the point of operation is where metal is being reshaped in dies from feed stock. Human interaction with machine systems necessitates mechanical design philosophy cognizant of safety. Point-of-operation safeguarding may consist of features and processes other than physical barrier guards. Guarding on a lawn mower may look different than guarding on a meat grinder. Nonetheless, they both have the same design objective -- prevent human contact with mechanical parts. This is typical of Meridian One's assignments.
