The lesson covers all the basics, from 2D projection, multi-view drawings, isometric projection, cross sectioning, linear dimensioning, basic tolerancing and alternate views.

Orthographic projection involves viewing an article being described in a technical drawing from different directions from the front, from a side, from above, from below or from any other viewing ...

In isometric views, all lines on each axis are parallel to each other, and the lines do not converge. Such drawings are commonly used in technical illustrations because of their clarity ...

It is often used to produce realistic drawings of an object. Isometric drawings, sometimes called isometric projections, are a good way of showing measurements and how components fit together.

When the diaphragm moves out, the volume of the pump chamber increases and causes the pressure within the chamber to decrease and draw in fluid. The inward stroke has the opposite effect, decreasing ...

The top is referred to as the ‘plan’. These drawings enable detailed measurements to be added for every section of the product. This isometric drawing shows the plan and front and side ...

It's one of the three types of muscle contractions (eccentric, concentric, and isometric)—and it’s often the contraction you’re most likely to forget about. You know concentric muscle ...

Stand upright with both arms out in front of you, bent at a 90 degree angle. Lock your hands together and squeeze as hard as you can. Hold the contraction for 15-30 seconds then relax. Expert tips: ...

But isometric training involves simply contracting your muscles, which generates force without needing to move your joints. The harder a muscle is contracted, the more forceful it becomes (and the ...

You can even improve your heart health by holding still and trying really hard not to move. Isometric training, as this is ...

Isometric training involves muscle contractions that generate force without joint movement. The harder the contraction, the more forceful the muscle becomes. Exercise is great for improving heart ...
