Conclusion 1. why do engineers place tolerances on dimensions? 2. what are the three types of tolerances that appear on dimensioned drawings? 3. what is the difference between a general and a specific tolerance, and how can you tell the difference on a drawing?

Tolerance enables the engineer to be informed when somethings requires replacement or if there is a drawback with too much war.

The three types of tolerances that appear on dimensioned drawings are limit, bilateral, and unilateral.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
