Mechanical Engineering

the process whereby liquid metal, such as gray iron, aluminum, or bronze, is poured into a mold, cooled, and solidified.

• Forming

• Casting

• Machining

• Finishing

_______________ refers to processes where a sharp metal tool removes material by cutting it. The most common machining methods are drilling, sawing, milling, and turning

Machining tools include drill presses, bandsaws, lathes, and ​

• milling machines
• sharpened blades
• pilot wheel

______________is used to bore round holes into a workpiece.

• band saw

• milling machine

• drill press

• lathe

The_____________________ is a measure of the tendency of the force to produce rotation of a body about a point or axis

Do mechanical engineers model systems using principles from different disciplines?

• No, mechanical engineers must apply the laws of thermodynamics

Newton’s three laws of motion:

• The forces of action and reaction between two objectives are equal, opposite, and collinear.

• Every object remains in a state of rest or uniform motion of constant velocity unless an external unbalanced force acts upon it.

• The first law is a formulation of the law of conservation of energy in the context of thermodynamic processes.

• An object of mass m, subject to a force F, experiences an acceleration in the same direction as the force with a magnitude directly proportional to the magnitude of the force and inversely proportional to the mass of the object.
