Five Easy Questions to Ask Your Mechanical Engineer

You don't want an amateur on the job when you're in the market for good mechanical engineering services. This isn't a game; you need a mechanical engineer who knows not just the basics, but the tricks of the trade.

But the basics of mechanical engineering are nothing to sneeze at. You need a mechanical engineer who won't look baffled when he needs to make unit conversions, or when you talk about the conservation of momentum.

So, with that in mind, here are five questions to spring on a mechanical engineer during an initial interview.

How would you go about determining the mass of this apple? When asking this question, make sure you have an apple handy. If you only have an orange, make sure you change the wording of your question. You don't want your mechanical engineer thinking you're a weirdo. But even if he does, telling you how to determine mass shouldn't be too hard. Simply place the apple to oscillate between a pair of springs in a weightless environment, and measure the resulting oscillation of the springs. Of course, if you don't have a properly calibrated set of mass-measuring springs, or a weightless environment, you could place the object in a scale designed for measuring mass.

Is acceleration a scalar quantity or a vector quantity? A good mechanical engineer knows his scalars and vectors. He also knows that acceleration (a change in the velocity of an object) is a vector quantity. That means it has two independent variables: Direction and magnitude. Their quantities muse be depicted on a graph. Scalars only have one dimension, and their quantities can be depicted on a line.

Which variables would you multiply to determine the momentum of a moving object? Momentum is a vector like acceleration, so it comprises two independent variables. Determining momentum means multiplying an object's mass by its speed. So a 1974 Chevy Impala moving at 120 kilometers per hour would have more momentum than a cocker spaniel skidding across a linoleum floor.

What's the standard unit of measurement for energy? Or power? Or planar angular measurement? Good mechanical engineering services require a comprehensive knowledge of units of measurement. Energy is measured in joules. Power, in watts. And planar angular measurement is expressed in radians.

What term would you use to describe the quantitative expression of the average kinetic energy an item contains? The answer is temperature. The higher the temperature of an object, the faster its atoms and molecules are moving around.

Mechanical Engineering, Mechanical Design and Drawing Services at Lowest Rates

Mechanical Engineering involves the Physical usage for mechanism and functioning, design, manufacturing, installation, operation and maintenance of mechanical systems such as boilers, condensers, heat engines, air conditioners & refrigerators, machine tools, thermal power stations etc.

Kinematics, dynamics, static, Energy conversion, Mechanics, Manufacturing and production, refrigeration and air conditioning are the foundation subjects of mechanical engineering. It also Engage its attention with other Engineering disciplines like Electrical engineering in electronics, Aeronautical Engineering in Fluid Mechanics, Civil Engineering in stress & Strain analysis, Computer Engineering in hardware manufacturing etc.

Accomplishing mechanical projects has always posed serious problems for companies, whether they need computer aided design such as electrical engineering, new industrial product design, or civil engineering of a new building.

Many people are familiar with online project marketplaces that connect businesses and individuals in need of services with skilled professionals to perform the work. Companies have long struggled with the engineering required to launch new products and build customized facilities. When you discuss the actual mechanical design of your next key product, or the structural engineering of a multi million dollar building, things cannot be left to chance and "close" is never close enough. Businesses need complete control over their projects, even if they are being outsourced. Mechanical engineers use the core principles as well as other knowledge in the field to design.

A Mechanical Engineer will:

~ Know how energy gets converted to useful power (thermodynamics).
~ Examine the wear and tear of machines and systems.
~ Prepare configurations and drawings of machines or machine parts.
~ Examine strength of material for a particular application.
~ Design advanced materials (machine design).
